JSF Runtime

PrimeFaces supports JSF 2.0, 2.1 and 2.2 runtimes at the same time using feature detection and by not having compile time dependency to a specific version. As a result some features are only available depending on the runtime.

A good example for runtime compatibility is the passthrough attributes, a JSF 2.2 specific feature to display dynamic attributes. In following page, pass through attribute placeholder only gets rendered if the runtime is JSF 2.2.

2.4 Hello World

Once you have added the primefaces jar to your classpath, you need to add the PrimeFaces namespace to your page to begin using the components. Here is a simple page like test.xhtml;

<!DOCTYPE html>

<h:head></h:head>

<h:body>

<p:editor />

</h:body>

</html>

When you run this page through Faces Servlet mapping e.g. *.jsf, you should see a rich text editor when you run the page with test.jsf.

Defines text direction, valid values are ltr and rtl.

AccordionPanel is a naming container thus prepends its id to its children by default, a false value turns this behavior off except for dynamic tabs.

Name of the client side widget.

Getting Started with Accordion Panel

Accordion panel consists of one or more tabs and each tab can group any content. Titles can also be defined with “title” facet.

<p:accordionPanel>

<p:tab title="First Tab Title">

<h:outputText value= "Lorem"/>

...More content for first tab

</p:tab>

<p:tab title="Second Tab Title">

<h:outputText value="Ipsum" />

</p:tab>

//any number of tabs

</p:accordionPanel>

Dynamic Content Loading

AccordionPanel supports lazy loading of tab content, when dynamic option is set true, only active tab contents will be rendered to the client side and clicking an inactive tab header will do an ajax request to load the tab contents.

This feature is useful to reduce bandwidth and speed up page loading time. By default activating a previously loaded dynamic tab does not initiate a request to load the contents again as tab is cached.

To control this behavior use cache option.

PrimeFaces User Guide

<p:accordionPanel dynamic="true">

//..tabs

</p:accordionPanel>

Client Side Callbacks

onTabChange is called before a tab is shown and onTabShow is called after. Both receive container element of the tab to show as the parameter.

<p:accordionPanel onTabChange="handleChange(panel)">

//..tabs

</p:accordionPanel>

//panel: new tab content container

}

</script>

Ajax Behavior Events

tabChange is the one and only ajax behavior event of accordion panel that is executed when a tab is toggled.

<p:accordionPanel>

<p:ajax event=”tabChange” listener=”#{bean.onChange}” />

</p:accordionPanel> public void onChange(TabChangeEvent event) {

//Tab activeTab = event.getTab();

//...

}

Your listener(if defined) will be invoked with an org.primefaces.event.TabChangeEvent instance that contains a reference to the new active tab and the accordion panel itself.

Dynamic Number of Tabs

When the tabs to display are not static, use the built-in iteration feature similar to ui:repeat.

<p:accordionPanel value=”#{bean.list}” var=”listItem”>

<p:tab title="#{listItem.propertyA}">

<h:outputText value= "#{listItem.propertyB}"/>

...More content

</p:tab>

</p:accordionPanel>

PrimeFaces User Guide

Disabled Tabs

A tab can be disabled by setting disabled attribute to true.

<p:accordionPanel>

<p:tab title="First Tab Title" disabled=”true”>

<h:outputText value= "Lorem"/>

...More content for first tab

</p:tab>

<p:tab title="Second Tab Title">

<h:outputText value="Ipsum" />

</p:tab>

//any number of tabs

</p:accordionPanel>

Multiple Selection

By default, only one tab at a time can be active, enable multiple mode to activate multiple tabs.

<p:accordionPanel multiple=”true”>

//tabs

</p:accordionPanel>

Boolean Enables serialization of values belonging to the partially processed components only.

Boolean Disables ajax behavior.

String Client side event to trigger ajax request.

Boolean If true, local values of input components to be updated within the ajax request would be reset.

PrimeFaces User Guide

Name Default

ignoreAutoUpdate false

Type Description

Boolean If true, components which autoUpdate="true" will not be updated for this request. If not specified, or the value is false, no such indication is made.

Getting Started with AjaxBehavior

AjaxBehavior is attached to the component to ajaxify.

<h:inputText value="#{bean.text}">

<p:ajax update="out" />

</h:inputText>

<h:outputText id="out" value="#{bean.text}" />

In the example above, each time the input changes, an ajax request is sent to the server. When the response is received output text with id "out" is updated with value of the input.

Listener

In case you need to execute a method on a backing bean, define a listener;

<h:inputText id="counter">

<p:ajax update="out" listener="#{counterBean.increment}"/>

</h:inputText>

<h:outputText id="out" value="#{counterBean.count}" /> public class CounterBean { private int count;

//getter setter public void increment() { count++;

}

Events

Default client side events are defined by components that support client behaviors, for input components it is onchange and for command components it is onclick. In order to override the dom event to trigger the ajax request use event option. In following example, ajax request is triggered when key is up on input field.

<h:inputText id="firstname" value="#{bean.text}">

<p:ajax update="out" event="keyup"/>

</h:inputText>

<h:outputText id="out" value="#{bean.text}" />

PrimeFaces User Guide

Getting Started with AjaxStatus

AjaxStatus uses facets to represent the request status. Most common used facets are start and

complete. Start facet will be visible once ajax request begins and stay visible until it’s completed.

Once the ajax response is received and page is updated, start facet gets hidden and complete facet shows up.

<p:ajaxStatus>

<f:facet name="start">

<p:graphicImage value="ajaxloading.gif" />

</f:facet>

<f:facet name="complete">

<h:outputText value="Done!" />

</f:facet>

</p:ajaxStatus>

Events

Here is the full list of available event names;

default: Initially visible when page is loaded.

start: Before ajax request begins.

success: When ajax response is received without error.

error: When ajax response is received with an http error.

complete: When everything finishes.

<p:ajaxStatus>

<f:facet name="error">

<h:outputText value="Error" />

</f:facet>

<f:facet name="success">

<h:outputText value="Success" />

</f:facet>

<f:facet name="default">

<h:outputText value="Idle" />

</f:facet>

<f:facet name="start">

<h:outputText value="Sending" />

</f:facet>

<f:facet name="complete">

<h:outputText value="Done" />

</f:facet>

</p:ajaxStatus>

Custom Events

Facets are the declarative way to use, if you’d like to implement advanced cases with scripting you can take advantage of on* callbacks which are the event handler counterparts of the facets.

<p:ajaxStatus onstart="alert('Start')" oncomplete="alert('End')"/>

PrimeFaces User Guide

A comman usage of programmatic approach is to implement a custom status dialog;

<p:ajaxStatus onstart="PF('status').show()" oncomplete="PF('status').hide()"/>

<p:dialog widgetVar="status" modal="true" closable="false">

Please Wait

</p:dialog>

Client Side API

Widget: PrimeFaces.widget.AjaxStatus

Method

trigger(event)

Params Return Type

event: Name of event. void

Description

Triggers given event.

Skinning

AjaxStatus is equipped with style and styleClass. Styling directly applies to a container element which contains the facets.

<p:ajaxStatus style="width:32px;height:32px" ... />

Tips

• Avoid updating ajaxStatus itself to prevent duplicate facet/callback bindings.

• Provide a fixed width/height to an inline ajaxStatus to prevent page layout from changing.

• Components like commandButton has an attribute (global) to control triggering of AjaxStatus.

• AjaxStatus also supports core JSF ajax requests of f:ajax as well.

Getting Started with AutoComplete

AutoComplete is an input component so it requires a value as usual. Suggestions are loaded by calling a server side completeMethod that takes a single string parameter which is the text entered.

<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}" /> public class Bean { private String text; public List<String> complete(String query) {

List<String> results = new ArrayList<String>(); for (int i = 0; i < 10; i++) results.add(query + i); return results;

}

//getter setter

}

PrimeFaces User Guide

Pojo Support

Most of the time, instead of simple strings you would need work with your domain objects, autoComplete supports this common use case with the use of a converter and data iterator.

Following example loads a list of players, itemLabel is the label displayed as a suggestion and itemValue is the submitted value. Note that when working with pojos, you need to plug-in your own converter.

<p:autoComplete value="#{playerBean.selectedPlayer}" completeMethod="#{playerBean.completePlayer}" var="player" itemLabel="#{player.name}" itemValue="#{player}" converter="playerConverter"/> public class PlayerBean { private Player selectedPlayer; public Player getSelectedPlayer() { return selectedPlayer;

} public void setSelectedPlayer(Player selectedPlayer) { this.selectedPlayer = selectedPlayer;

} public List<Player> complete(String query) {

List<Player> players = readPlayersFromDatasource(query); return players;

}

} public class Player { private String name;

//getter setter

}

Limiting the Results

Number of results shown can be limited, by default there is no limit.

<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}" maxResults="5" />

Minimum Query Length

By default queries are sent to the server and completeMethod is called as soon as users starts typing at the input text. This behavior is tuned using the minQueryLength attribute.

PrimeFaces User Guide

<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}" minQueryLength="3" />

With this setting, suggestions will start when user types the 3rd character at the input field.

Query Delay

AutoComplete is optimized using queryDelay option, by default autoComplete waits for 300 milliseconds to query a suggestion request, if you’d like to tune the load balance, give a longer value. Following autoComplete waits for 1 second after user types an input.

<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}" queryDelay="1000" />

Custom Content

AutoComplete can display custom content by nesting columns.

<p:autoComplete value="#{autoCompleteBean.selectedPlayer}" completeMethod="#{autoCompleteBean.completePlayer}" var="p" itemValue="#{p}" converter="player">

<p:column>

<p:graphicImage value="/images/barca/#{p.photo}" width="40" height="50"/>

</p:column>

<p:column>

#{p.name} - #{p.number}

</p:column>

</p:autoComplete>

Dropdown Mode

When dropdown mode is enabled, a dropdown button is displayed next to the input field, clicking this button will do a search with an empty query, a regular completeMethod implementation should load all available items as a response.

<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}" dropdown="true" />

Multiple Selection

AutoComplete supports multiple selection as well, to use this feature set multiple option to true and define a list as your backend model. Following example demonstrates multiple selection with custom content support.

PrimeFaces User Guide

<p:autoComplete id="advanced" value="#{autoCompleteBean.selectedPlayers}" completeMethod="#{autoCompleteBean.completePlayer}"

var="p" itemLabel="#{p.name}" itemValue="#{p}" converter="player" multiple="true">

<p:column style="width:20%;text-align:center">

<p:graphicImage value="/images/barca/#{p.photo}"/>

</p:column>

<p:column style="width:80%">

#{p.name} - #{p.number}

</p:column>

</p:autoComplete> public class AutoCompleteBean { private List<Player> selectedPlayers;

//...

}

Caching

Suggestions can be cached on client side so that the same query does not do a request which is likely to return same suggestions again. To enable this, set cache option to true. There is also a

cacheTimeout option to configure how long it takes to clear a cache automatically.

<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}" cache="true"/>

Ajax Behavior Events

Instead of waiting for user to submit the form manually to process the selected item, you can enable instant ajax selection by using the itemSelect ajax behavior. Example below demonstrates how to display a message about the selected item instantly.

PrimeFaces User Guide

<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}">

<p:ajax event="itemSelect" listener="bean.handleSelect" update="msg" />

</p:autoComplete>

<p:messages id=”msg” /> public class Bean { public void handleSelect(SelectEvent event) {

Object item = event.getObject();

FacesMessage msg = new FacesMessage("Selected", "Item:" + item);

}

//...

}

Your listener(if defined) will be invoked with an org.primefaces.event.Select instance that contains a reference to the selected item. Note that autoComplete also supports events inherited from regular input text such as blur, focus, mouseover in addition to itemSelect. Similarly, itemUnselect event is provided for multiple autocomplete when an item is removed by clicking the remove icon. In this case org.primefaces.event.Unselect instance is passed to a listener if defined.

• Do not forget to use a converter when working with pojos.

• Enable forceSelection if you would like to accept values only from suggested list.

• Increase query delay to avoid unnecessary load to server as a result of user typing fast.

• Use emptyMessage option to provide feedback to the users that there are no suggestions.

• Enable caching to avoid duplicate queries.

Getting started with Barcode

Barcode type should be provided along with the value to display. Supported formats are;

• int2of5

• codabar

• code39

• code128

• ean8

• ean13

• upca

• postnet

• pdf417

• datamatrix

• qr

PrimeFaces User Guide

<p:barcode value="0123456789" type="int2of5" />

Value can also be retrieved from a backend value.

<p:barcode value="#{bean.barcodeValue}" type="int2of5" />

Format

Default display format is svg and other possible option is png. In case the client browser does not support svg e.g. IE8, barcode automatically chooses png format.

<p:barcode value="#{bean.barcodeValue}" type="int2of5" format="png" />

Orientation

In order to change the orientation, choose the angle from the 4 pre-defined values.

<p:barcode value="#{bean.barcodeValue}" type="int2of5" orientation="90"/>

Dependencies

Barcode component uses barcode4j library underneath except QR code support, which is handled by qrgen library. Following versions are supported officially.

<artifactId>qrgen</artifactId>

</dependency>

<groupId>net.sf.barcode4j</groupId>

<artifactId>barcode4j-light</artifactId>

</dependency>

* barcode4j 2.1 does not exist in maven central repository so manual installation is necessary for maven users.

PrimeFaces User Guide

Description

Identifier of the component to block.

Blocks the UI by default when enabled.

Getting Started with BlockUI

BlockUI requires trigger and block attributes to be defined. With the special ajax integration, ajax requests whose source are the trigger components will block the ui onstart and unblock oncomplete.

Example below blocks the ui of the panel when saveBtn is clicked and unblock when ajax response is received.

<p:panel id="pnl" header="My Panel">

//content

<p:commandButton id="saveBtn" value="Save" />

</p:panel>

<p:blockUI block="pnl" trigger="saveBtn" />

Multiple triggers are defined as a comma separated list.

<p:blockUI block="pnl" trigger="saveBtn,deleteBtn,updateBtn" />

Custom Content

In order to display custom content like a loading text and animation, place the content inside the blockUI.

<p:dataTable id="dataTable" var="car" value="#{tableBean.cars}"

paginator="true" rows="10">

<p:column>

<f:facet name="header">

<h:outputText value="Model" />

</f:facet>

<h:outputText value="#{car.model}" />

</p:column>

//more columns

</p:dataTable>

<p:blockUI block="dataTable" trigger="dataTable">

PrimeFaces User Guide

Getting Started with BreadCrumb

Steps are defined as child menuitem components in breadcrumb.

<p:breadCrumb>

<p:menuitem label="Categories" url="#" />

<p:menuitem label="Sports" url="#" />

//more menuitems

</p:breadCrumb>

Dynamic Menus

Menus can be created programmatically as well, see the dynamic menus part in menu component section for more information and an example.

Skinning

Breadcrumb resides in a container element that style and styleClass options apply. Following is the list of structural style classes;

Style Class

.ui-breadcrumb

.ui-breadcrumb .ui-menu-item-link

.ui-breadcrumb .ui-menu-item-text

.ui-breadcrumb-chevron

Applies

Main breadcrumb container element.

Each menuitem.

Each menuitem label.

Seperator of menuitems.

As skinning style classes are global, see the main theming section for more information.

Tips

• If there is a dynamic flow, use model option instead of creating declarative p:menuitem components and bind your MenuModel representing the state of the flow.

• Breadcrumb can do ajax/non-ajax action requests as well since p:menuitem has this option. In this case, breadcrumb must be nested in a form.

• url option is the key for a menuitem, if it is defined, it will work as a simple link. If you’d like to use menuitem to execute command with or without ajax, do not define the url option.

String

Unique id of the cache region, defaults to view id.

Unique id of the cache entry in region, defaults to client id of component.

Getting Started with Cache

A cache store is required to use the cache component, two different providers are supported as cache implementation; EHCache and Hazelcast. Provider is configured via a context-param.

<context-param>

<param-name>primefaces.CACHE_PROVIDER</param-name>

<param-value>org.primefaces.cache.EHCacheProvider</param-value>

</context-param>

Here is a sample ehcache.xml to configure cache regions, there are two regions in this configuration.

PrimeFaces User Guide

<?xml version="1.0" encoding="UTF-8"?>

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:noNamespaceSchemaLocation="ehcache.xsd"

updateCheck="true" monitoring="autodetect"

dynamicConfig="true">

<defaultCache

maxEntriesLocalDisk="10000000"

diskExpiryThreadIntervalSeconds="120"

</defaultCache>

<cache name="testcache"

diskSpoolBufferSizeMB="30"

maxEntriesLocalDisk="10000000"

diskExpiryThreadIntervalSeconds="120"

memoryStoreEvictionPolicy="LRU">

</cache>

</ehcache>

After the configuration, at UI side, the cached part needs to be wrapped inside the p:cache component.

<p:cache>

//content to cache

</p:cache>

Once the page is loaded initially, content inside p:cache component is cached inside the cache region of the cache provider. Postbacks on the same page or reopening the page retrieve the output from cache instead of rendering the content regularly.

Cache Provider API

CacheProvider can be accessed via;

RequestContext.getCurrentInstance().getApplicationContext().getCacheProvider()

For example using this API, all cache regions can be cleaned using clear() method. Refer to javadoc of CacheProvider for the full list of available methods.

Getting Started with Calendar

Value of the calendar should be a java.util.Date.

<p:calendar value="#{dateBean.date}"/>

public class DateBean { private Date date;

//Getter and Setter

}

Display Modes

Calendar has two main display modes, popup (default) and inline.

Inline

<p:calendar value="#{dateBean.date}" mode="inline" />

PrimeFaces User Guide

Popup

<p:calendar value="#{dateBean.date}" mode="popup" />

showOn option defines the client side event to display the calendar. Valid values are;

• focus: When input field receives focus

• button: When popup button is clicked

• both: Both focus and button cases

Popup Button

<p:calendar value="#{dateBean.date}" mode="popup" showOn="button" />

PrimeFaces User Guide

Popup Icon Only

<p:calendar value="#{dateBean.date}" mode="popup" showOn="button" popupIconOnly="true" />

Paging

Calendar can also be rendered in multiple pages where each page corresponds to one month. This feature is tuned with the pages attribute.

<p:calendar value="#{dateController.date}" pages="3"/>

Localization

By default locale information is retrieved from the view’s locale and can be overridden by the locale attribute. Locale attribute can take a locale key as a String or a java.util.Locale instance. Default language of labels are English and you need to add the necessary translations to your page manually as PrimeFaces does not include language translations. PrimeFaces Wiki Page for

PrimeFacesLocales is a community driven page where you may find the translations you need.

Please contribute to this wiki with your own translations.

https://code.google.com/p/primefaces/wiki/PrimeFacesLocales

Translation is a simple javascript object, we suggest adding the code to a javascript file and include in your application. Following is a Turkish calendar.

PrimeFaces User Guide

<h:outputScript name=”path_to_your_translations.js” />

<p:calendar value="#{dateController.date}" locale="tr" navigator="true" showButtonPanel="true"/>

To override calculated pattern from locale, use the pattern option;

<p:calendar value="#{dateController.date1}" pattern="dd.MM.yyyy"/>

<p:calendar value="#{dateController.date2}" pattern="yy, M, d"/>

<p:calendar value="#{dateController.date3}" pattern="EEE, dd MMM, yyyy"/>

Effects

Various effects can be used when showing and hiding the popup calendar, options are; show, slideDown, fadeIn, blind, bounce, clip, drop, fold and slide.

Ajax Behavior Events

Calendar provides a dateSelect ajax behavior event to execute an instant ajax selection whenever a date is selected. If you define a method as a listener, it will be invoked by passing an

org.primefaces.event.SelectEvent instance.

<p:calendar value="#{calendarBean.date}">

<p:ajax event=”dateSelect” listener=”#{bean.handleDateSelect}” update=”msg” />

</p:calendar>

<p:messages id="msg" />

PrimeFaces User Guide public void handleDateSelect(SelectEvent event) {

Date date = (Date) event.getObject();

//Add facesmessage

}

In popup mode, calendar also supports regular ajax behavior events like blur, keyup and more.

Another handy event is the viewChange that is fired when month and year changes. An instance of

org.primefaces.event.DateViewChangeEvent is passed to the event listener providing the current month and year information.

Date Ranges

Using mindate and maxdate options, selectable dates can be restricted. Values for these attributes can either be a string or a java.util.Date.

<p:calendar value="#{dateBean.date}" mode="inline"

mindate="07/10/2010" maxdate="07/15/2010"/>

Navigator

Navigator is an easy way to jump between months/years quickly.

<p:calendar value="#{dateBean.date}" mode="inline" navigator="true" />

TimePicker

TimePicker functionality is enabled by adding time format to your pattern.

<p:calendar value="#{dateBean.date}" pattern=”MM/dd/yyyy HH:mm” />

PrimeFaces User Guide

Advanced Customization

Use beforeShowDay javascript callback to customize the look of each date. The function returns an array with two values, first one is flag to indicate if date would be displayed as enabled and second parameter is the optional style class to add to date cell. Following example disabled tuesdays and fridays.

<p:calendar value="#{dateBean.date}" beforeShowDay="tuesdaysAndFridaysOnly" />

Function tuesdaysAndFridaysDisabled(date) { var day = date.getDay(); return [(day != 2 && day != 5), '']

}

Calendar has a built-in mask feature similar to the InputMask component. Set mask option to true to enable mask support.

Getting Started with Captcha

Catpcha is implemented as an input component with a built-in validator that is integrated with reCaptcha. First thing to do is to sign up to reCaptcha to get public&private keys. Once you have the keys for your domain, add them to web.xml as follows;

<context-param>

<param-name>primefaces.PRIVATE_CAPTCHA_KEY</param-name>

<param-value>YOUR_PRIVATE_KEY</param-value>

</context-param>

<context-param>

<param-name>primefaces.PUBLIC_CAPTCHA_KEY</param-name>

<param-value>YOUR_PUBLIC_KEY</param-value>

</context-param>

That is it, now you can use captcha as follows;

<p:captcha />

Themes

Captcha features following built-in themes for look and feel customization;

- red (default)

- white

- blackglass

- clean

Themes are applied via the theme attribute.

PrimeFaces User Guide

<p:captcha theme="white"/>

Languages

Text instructions displayed on captcha is customized with the language attribute. Below is a captcha with Turkish text.

<p:captcha language="tr"/>

Overriding Validation Messages

By default captcha displays it’s own validation messages, this can be easily overridden by the JSF message bundle mechanism. Corresponding keys are;

Summary

Detail primefaces.captcha.INVALID

primefaces.captcha.INVALID_detail

Tips

• Use label option to provide readable error messages in case validation fails.

• Enable secure option to support https otherwise browsers will give warnings.

• See http://www.google.com/recaptcha/learnmore to learn more about how reCaptcha works.

Getting Started with Carousel

Carousel has two main use-cases; data and general content display. To begin with data iteration let’s use a list of cars to display with carousel.

public class Car { private String model; private int year; private String manufacturer; private String color;

...

} public class CarBean { private List<Car> cars; public CarListController() { cars = new ArrayList<Car>(); cars.add(new Car("myModel", 2005, "ManufacturerX", "blue"));

//add more cars

}

//getter setter

}

PrimeFaces User Guide

<p:carousel value="#{carBean.cars}" var="car" itemStyle="width:200px">

<p:graphicImage value="/images/cars/#{car.manufacturer}.jpg"/>

<h:outputText value="Model: #{car.model}" />

<h:outputText value="Year: #{car.year}" />

<h:outputText value="Color: #{car.color}" />

</p:carousel>

Carousel iterates through the cars collection and renders it’s children for each car, note that you also need to define a width for each item.

Limiting Visible Items

Bu default carousel lists its items in pages with size 3. This is customizable with the rows attribute.

<p:carousel value="#{carBean.cars}" var="car" numVisible="1" itemStyle="width:200px" >

...

</p:carousel>

Effects

Paging happens with a slider effect by default and following easing options are supported.

• backBoth

• backIn

• backOut

• bounceBoth

• bounceIn

• bounceOut

• easeBoth

• easeBothStrong

SlideShow

Carousel can display the contents in a slideshow, for this purpose autoPlayInterval and circular attributes are used. Following carousel displays a collection of images as a slideshow.

<p:carousel autoPlayInterval="2000" rows="1" effect="easeInStrong" circular="true" itemStyle=”width:200px” >

<p:graphicImage value="/images/nature1.jpg"/>

<p:graphicImage value="/images/nature2.jpg"/>

<p:graphicImage value="/images/nature3.jpg"/>

<p:graphicImage value="/images/nature4.jpg"/>

</p:carousel>

Content Display

Another use case of carousel is tab based content display.

<p:carousel rows="1" itemStyle="height:200px;width:600px;">

<p:tab title="Godfather Part I">

<h:panelGrid columns="2" cellpadding="10">

<p:graphicImage value="/images/godfather/godfather1.jpg" />

<h:outputText value="The story begins as Don Vito ..." />

</h:panelGrid>

</p:tab>

<p:tab title="Godfather Part II">

<h:panelGrid columns="2" cellpadding="10">

<p:graphicImage value="/images/godfather/godfather2.jpg" />

<h:outputText value="Francis Ford Coppola's ..."/>

</h:panelGrid>

</p:tab>

<p:tab title="Godfather Part III">

<h:panelGrid columns="2" cellpadding="10">

<p:graphicImage value="/images/godfather/godfather3.jpg" />

<h:outputText value="After a break of ..." />

</h:panelGrid>

</p:tab>

</p:carousel>

Item Selection

Sample below selects an item from the carousel and displays details within a dialog.

<h:form id=”form">

<p:carousel value="#{carBean.cars}" var="car" itemStyle=”width:200px” >

<p:graphicImage value="/images/cars/#{car.manufacturer}.jpg"/>

<p:commandLink update=":form:detail" oncomplete="PF('dlg').show()">

<h:outputText value="Model: #{car.model}" />

<f:setPropertyActionListener value="#{car}" target="#{carBean.selected}" />

3.14.15 Extender

Chart API provide high level access to commonly used jqplot options however there are many more customization options available in jqplot. Extender feature provide access to low level apis to do advanced customization by enhancing the configuration object, here is an example to increase shadow depth of the line series where model's extender property is set to "ext".

<p:chart type="line" model="#{bean.model}" /> function ext() {

//this = chart widget instance

//this.cfg = options this.cfg.seriesDefaults = { shadowDepth: 5

};

}

Getting started with CommandButton

CommandButton usage is similar to standard commandButton, by default commandButton submits its enclosing form with ajax.

<p:commandButton value="Save" actionListener="#{bookBean.saveBook}" /> public class BookBean {

public void saveBook() {

//Save book

}

Reset Buttons

Reset buttons do not submit the form, just resets the form contents.

<p:commandButton type="reset" value="Reset" />

Push Buttons

Push buttons are used to execute custom javascript without causing an ajax/non-ajax request. To create a push button set type as "button".

<p:commandButton type="button" value="Alert" onclick="alert(‘Prime’)" />

AJAX and Non-AJAX

CommandButton has built-in ajax capabilities, ajax submit is enabled by default and configured using ajax attribute. When ajax attribute is set to false, form is submitted with a regular full page refresh.

T h e update attribute is used to partially update other component(s) after the ajax response is received. Update attribute takes a comma or white-space separated list of JSF component ids to be updated. Basically any JSF component, not just PrimeFaces components should be updated with the

Ajax response. In the following example, form is submitted with ajax and display outputText is updated with the ajax response.

<h:form>

<h:inputText value="#{bean.text}" />

<p:commandButton value="Submit" update="display"/>

<h:outputText value="#{bean.text}" id="display" />

</h:form>

Tip: You can use the ajaxStatus component to notify users about the ajax request.

Icons

An icon on a button is provided using icon option. iconPos is used to define the position of the button which can be “left” or “right”.

<p:commandButton icon="disk"/>

.disk is a simple css class with a background property;

.disk { background-image: url(‘disk.png’) !important;

String Defines text direction, valid values are ltr and rtl.

Boolean When enabled, confirmDialog becomes a shared for other components that require confirmation.

Getting started with ConfirmDialog

ConfirmDialog has two modes; global and non-global. Non-Global mode is almost same as the dialog component used with a simple client side api, show() and hide().

<h:form>

<p:commandButton type="button" onclick="PF('cd').show()" />

<p:confirmDialog message="Are you sure about destroying the world?" header="Initiating destroy process" severity="alert" widgetVar="cd">

<p:commandButton value="Yes Sure" actionListener="#{buttonBean.destroyWorld}" update="messages" oncomplete="PF('cd').hide()"/>

<p:commandButton value="Not Yet" onclick="PF('cd').hide();" type="button" />

</p:confirmDialog>

</h:form>

Message and Severity

Message can be defined in two ways, either via message option or message facet. Message facet is useful if you need to place custom content instead of simple text. Note that header can also be defined using the header attribute or the header facet. Severity defines the icon to display next to the message, default severity is alert and the other option is info.

<p:confirmDialog widgetVar="cd" header=”Confirm”>

<f:facet name="message">

<h:outputText value="Are you sure?" />

</f:facet>

//content

</p:confirmDialog>

Global

Creating a confirmDialog for a specific action is a repetitive task, to solve this global confirmDialog which is a singleton has been introduced. Trigger components need to have p:confirm behavior to

119

PrimeFaces User Guide use the confirm dialog. Component that trigger the actual command in dialog must have ui-confirm-

dialog-yes style class, similarly component to cancel the command must have ui-confirm-dialog-no.

At the moment p:confirm is supported by p:commandButton and p:commandLink.

<p:growl id="messages" />

<p:commandButton value="Save" actionListener="#{bean.save}" update="messages">

<p:confirm header="Confirmation" message="Sure?" icon="ui-icon-alert"/>

</p:commandButton>

PrimeFaces User Guide

Getting started with ContextMenu

ContextMenu is created with submenus and menuitems. Optional for attribute defines which component the contextMenu is attached to. When for is not defined, contextMenu is attached to the page meaning, right-click on anywhere on page will display the menu.

<p:contextMenu>

<p:menuitem value="Save" actionListener="#{bean.save}" update="msg"/>

<p:menuitem value="Delete" actionListener="#{bean.delete}" ajax="false"/>

<p:menuitem value="Go Home" url= " " target="_blank"/>

</p:contextMenu

ContextMenu example above is attached to the whole page and consists of three different menuitems with different use cases. First menuitem triggers an ajax action, second one triggers a non-ajax action and third one is used for navigation.

Attachment

ContextMenu can be attached to any JSF component, this means right clicking on the attached component will display the contextMenu. Following example demonstrates an integration between contextMenu and imageSwitcher, contextMenu here is used to navigate between images.

<p:imageSwitch id="images" widgetVar="gallery" slideshowAuto="false">

<p:graphicImage value="/images/nature1.jpg" />

<p:graphicImage value="/images/nature2.jpg" />

<p:graphicImage value="/images/nature3.jpg" />

<p:graphicImage value="/images/nature4.jpg" />

</p:imageSwitch>

<p:contextMenu for="images">

<p:menuitem value="Previous" url="#" onclick="PF('gallery').previous()" />

<p:menuitem value="Next" url="#" onclick="PF('gallery').next()" />

</p:contextMenu>

Now right-clicking anywhere on an image will display the contextMenu like;

Data Components

Data components like datatable, tree and treeTable has special integration with context menu, see the documentation of these component for more information.

126

Getting started with Dashboard

Dashboard is backed by a DashboardModel and consists of panel components.

PrimeFaces User Guide

<p:dashboard model="#{bean.model}">

<p:panel id="sports">

//Sports Content

</p:panel>

<p:panel id="finance">

//Finance Content

</p:panel>

//more panels like lifestyle, weather, politics...

</p:dashboard>

Dashboard model simply defines the number of columns and the widgets to be placed in each column. See the end of this section for the detailed Dashboard API.

public class Bean { private DashboardModel model; public Bean() { model = new DefaultDashboardModel();

DashboardColumn column1 = new DefaultDashboardColumn();

DashboardColumn column2 = new DefaultDashboardColumn();

DashboardColumn column3 = new DefaultDashboardColumn(); column1.addWidget("sports"); column1.addWidget("finance"); column2.addWidget("lifestyle"); column2.addWidget("weather"); column3.addWidget("politics"); model.addColumn(column1); model.addColumn(column2); model.addColumn(column3);

}

State

Dashboard is a stateful component, whenever a widget is reordered dashboard model will be updated, by persisting the user changes so you can easily create a stateful dashboard.

Ajax Behavior Events

“reorder” is the one and only ajax behavior event provided by dashboard, this event is fired when dashboard panels are reordered. A defined listener will be invoked by passing an

org.primefaces.event.DashboardReorderEvent instance containing information about reorder.

Following dashboard displays a message about the reorder event

127

PrimeFaces User Guide

<p:dashboard model="#{bean.model}">

<p:ajax event=”reorder” update=”messages” listener=”#{bean.handleReorder}” />

//panels

</p:dashboard>

<p:growl id="messages" /> public class Bean {

...

public void handleReorder(DashboardReorderEvent event) {

String widgetId = event.getWidgetId(); int widgetIndex = event.getItemIndex(); int columnIndex = event.getColumnIndex(); int senderColumnIndex = event.getSenderColumnIndex();

//Add facesmessage

}

If a widget is reordered in the same column, senderColumnIndex will be null. This field is populated only when a widget is transferred to a column from another column. Also when the listener is invoked, dashboard has already updated it’s model.

Disabling Dashboard

If you’d like to disable reordering feature, set disabled option to true.

<p:dashboard disabled="true" ...>

//panels

</p:dashboard>

Toggle, Close and Options Menu

Widgets presented in dashboard can be closable, toggleable and have options menu as well, dashboard doesn’t implement these by itself as these features are already provided by the panel component. See panel component section for more information.

<p:dashboard model="#{dashboardBean.model}">

<p:panel id="sports" closable="true" toggleable="true">

//Sports Content

</p:panel>

</p:dashboard>

New Widgets

Draggable component is used to add new widgets to the dashboard. This way you can add new panels from outside of the dashboard.

128

PrimeFaces User Guide

<p:dashboard model="#{dashboardBean.model}" id="board">

//panels

</p:dashboard>

<p:panel id="newwidget" />

<p:draggable for="newwidget" helper="clone" dashboard="board" />

PreProcessor for the exported document.

PostProcessor for the exported document.

Character encoding to use

When enabled, only selection would be exported.

Getting Started with DataExporter

DataExporter is nested in a UICommand component such as commandButton or commandLink. For pdf exporting itext and for xls exporting poi libraries are required in the classpath. Target must point to a PrimeFaces Datatable. Assume the table to be exported is defined as;

<p:dataTable id="tableId" ...>

//columns

</p:dataTable>

Excel export

<p:commandButton value="Export as Excel" ajax="false">

<p:dataExporter type="xls" target="tableId" fileName="cars"/>

</p:commandButton>

<p:dataExporter type="csv" target="tableId" fileName="cars"/>

</p:commandButton>

XML export

<p:commandButton value="Export as XML" ajax="false" >

<p:dataExporter type="xml" target="tableId" fileName="cars"/>

</p:commandLink>

PageOnly

By default dataExporter works on whole dataset, if you’d like export only the data displayed on current page, set pageOnly to true.

<p:dataExporter type="pdf" target="tableId" fileName="cars" pageOnly="true"/>

Excluding Columns

In case you need one or more columns to be ignored set exportable option of column to false.

<p:column exportable="false">

//...

</p:column>

Monitor Status

DataExport is a non-ajax process so ajaxStatus component cannot apply. See FileDownload

Monitor Status section to find out how monitor export process. Same solution applies to data export as well.

Pre and Post Processors

Processors are handy to customize the exported document (e.g. add logo, caption ...). PreProcessors are executed before the data is exported and PostProcessors are processed after data is included in the document. Processors are simple java methods taking the document as a parameter.

Change Excel Table Header

First example of processors changes the background color of the exported excel’s headers.

132

<h:commandButton value="Export as XLS">

<p:dataExporter type="xls" target="tableId" fileName="cars" postProcessor="#{bean.postProcessXLS}"/>

</h:commandButton>

PrimeFaces User Guide public void postProcessXLS(Object document) {

HSSFWorkbook wb = (HSSFWorkbook) document;

HSSFSheet sheet = wb.getSheetAt(0);

HSSFRow header = sheet.getRow(0);

HSSFCellStyle cellStyle = wb.createCellStyle(); cellStyle.setFillForegroundColor(HSSFColor.GREEN.index); cellStyle.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND); for(int i=0; i < header.getPhysicalNumberOfCells();i++) { header.getCell(i).setCellStyle(cellStyle);

}

Add Logo to PDF

This example adds a logo to the PDF before exporting begins.

<h:commandButton value="Export as PDF">

<p:dataExporter type="pdf" target="tableId" fileName="cars" preProcessor="#{bean.preProcessPDF}"/>

</h:commandButton> public void preProcessPDF(Object document) throws IOException,

Getting started with the DataGrid

A list of cars will be used throughout the datagrid, datalist and datatable examples.

public class Car { private String model; private int year; private String manufacturer; private String color;

...

}

135

PrimeFaces User Guide

The code for CarBean that would be used to bind the datagrid to the car list.

public class CarBean { private List<Car> cars; public CarBean() { cars = new ArrayList<Car>(); cars.add(new Car("myModel",2005,"ManufacturerX","blue"));

//add more cars

} public List<Car> getCars() { return cars;

<p:graphicImage value="/images/cars/#{car.manufacturer}.jpg"/>

<h:outputText value="#{car.year}" />

</h:panelGrid>

</p:panel>

</p:column>

</p:dataGrid>

This datagrid has 3 columns and 12 rows. As datagrid extends from standard UIData, rows correspond to the number of data to display not the number of rows to render so the actual number of rows to render is rows/columns = 4. As a result datagrid is displayed as;

136

PrimeFaces User Guide

Ajax Pagination

DataGrid has a built-in paginator that is enabled by setting paginator option to true.

<p:dataGrid var="car" value="#{carBean.cars}" columns="3" rows="12" paginator="true">

...

</p:dataGrid>

Paginator Template

Paginator is customized using paginatorTemplateOption that accepts various keys of UI controls.

Note that this section applies to dataGrid, dataList and dataTable.

• FirstPageLink

• LastPageLink

• PreviousPageLink

• NextPageLink

• PageLinks

• CurrentPageReport

• RowsPerPageDropdown

Note that {RowsPerPageDropdown} has it’s own template, options to display is provided via rowsPerPageTemplate attribute (e.g. rowsPerPageTemplate="9,12,15").

Also {CurrentPageReport} has it’s own template defined with currentPageReportTemplate option.

You can use {currentPage},{totalPages},{totalRecords},{startRecord},{endRecord} keyword within currentPageReportTemplate. Default is {currentPage} of{totalPages}. Default UI is; w hich corresponds to the following template.

"{FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink}"

Here are more examples based on different templates;

" {CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink}

{LastPageLink} {RowsPerPageDropdown}"

" {PreviousPageLink} {CurrentPageReport} {NextPageLink}"

Paginator Position

Paginator can be positoned using paginatorPosition attribute in three different locations, "top",

"bottom" or "both" (default).

137

PrimeFaces User Guide

Custom Content in Paginator

Custom content can be placed inside a paginator using a facet name matching a token in the template.

<p:dataTable paginatorTemplate="{CurrentPageReport} {MyContent} ...">

<f:facet name="{MyContent}">

//Any content here

</f:facet>

//...

</p:dataTable>

Selecting Data

Selection of data displayed in datagrid is very similar to row selection in datatable, you can access the current data using the var reference. Here is an example to demonstrate how to select data from datagrid and display within a dialog with ajax.

<h:form id="carForm">

<p:dataGrid var="car" value="#{carBean.cars}" columns="3" rows="12">

<p:panel header="#{car.model}">

Getting started with the DataList

Since DataList is a data iteration component, it renders it’s children for each data represented with

var option. See itemType section for more information about the possible values.

<p:dataList value="#{carBean.cars}" var="car" itemType="disc">

#{car.manufacturer}, #{car.year}

</p:dataList>

Ordered Lists

DataList displays the data in unordered format by default, if you’d like to use ordered display set

type option to "ordered".

142

PrimeFaces User Guide

<p:dataList value="#{carBean.cars}" var="car" type="ordered">

#{car.manufacturer}, #{car.year}

</p:dataList>

Item Type

itemType defines the bullet type of each item. For ordered lists, in addition to commonly used

decimal type, following item types are available;

- A

- a

- i

And for unordered lists, available values are;

- disc

- circle

- square

Definition Lists

Third type of dataList is definition lists that display inline description for each item, to use definition list set type option to "definition". Detail content is provided with the facet called

"description".

<p:dataList value="#{carBean.cars}" var="car" type="definition">

Model: #{car.model}, Year: #{car.year}

<f:facet name="description">

<p:graphicImage value="/images/cars/#{car.manufacturer}.jpg"/>

</f:facet>

</p:dataList>

Ajax Pagination

DataList has a built-in paginator that is enabled by setting paginator option to true.

<p:dataList value="#{carBean.cars}" var="car" paginator="true" rows="10">

#{car.manufacturer}, #{car.year}

</p:dataList>

Pagination configuration and usage is same as dataGrid, see pagination section in dataGrid documentation for more information and examples.

Boolean Defines if lazy loading is enabled for the data component.

Integer

Defines pixel height of the viewport in inline mode.

Percentage height of the buffer between the bottom of the page and the scroll position to initiate the load for the new chunk. Value is defined in integer and default is 10 meaning load would happen after 90% of the viewport is scrolled down.

Getting started with the DataScroller

DataScroller requires a collection of data to display, when the page is scrolled down, datascroller will do a request with ajax to fetch the new chunk of data and append them at the bottom.

<p:dataScroller value="#{carBean.cars}" var="car" chunkSize="10">

#{car.manufacturer}

//more content

</p:dataList>

Scroll Mode

Default element whose scrollbar is monitored is page itself, mode option is used to customize the scroll target. Two possible options for the mode attribute are “document” and “inline”. Document mode is default and inline mode listens to the scroll event of the datascroller container itself.

146

PrimeFaces User Guide

<p:dataScroller value="#{carBean.cars}" var="car" mode="inline" chunkSize="10">

#{car.manufacturer}

//more content

</p:dataList>

Loader

In case of scrolling, a UI element such as button can defined as the loader so that new data is loaded when the loader element is clicked. Loader component is defined using "loader" facet.

<p:dataScroller value="#{carBean.cars}" var="car" mode="inline" chunkSize="10">

#{car.manufacturer}

//more content

<f:facet name="loader">

<p:commandButton type="button" value="View More" />

</f:facet>

</p:dataList>

Lazy Loading

Lazy loading is enabled by enabling the lazy attribute and providing a LazyDataModel instance as the value. Refer to lazy load example in DataTable for an example about LazyDataModel.

<p:dataScroller value="#{carBean.lazyModel}" var="car" lazy="true">

#{car.manufacturer}

//more content

</p:dataList>

Header

Header of the component is defined using header facet.

<p:dataScroller value="#{carBean.lazyModel}" var="car">

Getting started with the DataTable

We will be using the same Car and CarBean classes described in DataGrid section.

<p:dataTable var="car" value="#{carBean.cars}">

<p:column>

<f:facet name="header">

<h:outputText value="Model" />

</f:facet>

<h:outputText value="#{car.model}" />

</p:column>

//more columns

</p:dataTable>

Header and Footer

Both datatable itself and columns can have custom content in their headers and footers using header and footer facets respectively. Alternatively for columns there are headerText and footerText shortcuts to display simple texts.

152

PrimeFaces User Guide

<p:dataTable var="car" value="#{carBean.cars}">

<f:facet name="header">

List of Cars

</f:facet>

<p:column>

<f:facet name="header">

Model

</f:facet>

#{car.model}

<f:facet name="footer">

8 digit code

</f:facet>

</p:column>

<p:column headerText="Year" footerText="1960-2010">

#{car.year}

</p:column>

//more columns

<f:facet name="footer">

In total there are #{fn:length(carBean.cars)} cars.

</f:facet>

</p:dataTable>

Pagination

DataTable has a built-in ajax based paginator that is enabled by setting paginator option to true, see pagination section in dataGrid documentation for more information about customization options.

<p:dataTable var="car" value="#{carBean.cars}" paginator="true" rows="10">

//columns

</p:dataTable>

Sorting

Defining sortBy attribute enables ajax based sorting on that particular column.

<p:dataTable var="car" value="#{carBean.cars}">

<p:column sortBy="#{car.model}" headerText="Model">

<h:outputText value="#{car.model}" />

</p:column>

...more columns

</p:dataTable>

Instead of using the default sorting algorithm which uses a java comparator, you can plug-in your own sort method as well.

public int sortByModel(Object car1, Object car2) {

//return -1, 0 , 1 if car1 is less than, equal to or greater than car2

}

153

PrimeFaces User Guide

<p:dataTable var="car" value="#{carBean.cars}">

<p:column sortBy="#{car.model}" sortFunction="#{carBean.sortByModel}" headerText="Model">

<h:outputText value="#{car.model}" />

</p:column>

...more columns

</p:dataTable>

Multiple sorting is enabled by setting sortMode to multiple. In this mode, clicking a sort column while metakey is on adds sort column to the order group.

<p:dataTable var="car" value="#{carBean.cars}" sortMode="multiple">

//columns

</p:dataTable>

DataTable can display data sorted by default, to implement this use the sortBy option of datatable and the optional sortOrder. Table below would be initially displayed as sorted by model.

<p:dataTable var="car" value="#{carBean.cars}" sortBy="#{car.model}">

<p:column sortBy="#{car.model}" headerText=”Model”>

<h:outputText value="#{car.model}" />

</p:column>

<p:column sortBy="#{car.year}" headerText="Year">

<h:outputText value="#{car.year}" />

</p:column>

...more columns

</p:dataTable>

Filtering

Ajax based filtering is enabled by setting filterBy at column level and providing a list to keep the filtered sublist. It is suggested to use a scope longer than request like viewscope to keep the filteredValue so that filtered list is still accessible after filtering.

<p:dataTable var="car" value="#{carBean.cars}" filteredValue="#{carBean.filteredCars}">

<p:column filterBy="#{car.model}" headerText="Model">

<h:outputText value="#{car.model}" />

</p:column>

...more columns

</p:dataTable>

Filtering is triggered with keyup event and filter inputs can be styled using filterStyle,

filterStyleClass attributes. If you’d like to use a dropdown instead of an input field to only allow predefined filter values use filterOptions attribute and a collection/array of selectitems as value. In addition, filterMatchMode defines the built-in matcher which is startsWith by default.

Following is a basic filtering datatable with these options demonstrated;

154

PrimeFaces User Guide

<p:dataTable var="car" value="#{carBean.cars}" filteredValue="#{carBean.filteredCars}" widgetVar="carsTable">

<f:facet name="header">

<p:outputPanel>

<h:outputText value="Search all fields:" />

<h:inputText id="globalFilter" onkeyup="PF('carsTable').filter()" />

</p:outputPanel>

</f:facet>

<p:column filterBy="#{car.model}" headerText="Model" filterMatchMode="contains">

<h:outputText value="#{car.model}" />

</p:column>

<p:column filterBy="#{car.year}" headerText="Year" footerText="startsWith">

<h:outputText value="#{car.year}" />

</p:column>

<p:column filterBy="#{car.manufacturer}" headerText="Manufacturer" filterOptions="#{carBean.manufacturerOptions}" filterMatchMode="exact">

<h:outputText value="#{car.manufacturer}" />

</p:column>

<p:column filterBy="#{car.color}" headerText="Color" filterMatchMode="endsWith">

<h:outputText value="#{car.color}" />

</p:column>

<p:column filterBy="#{car.price}" headerText="Price" filterMatchMode="exact">

<h:outputText value="#{car.price}" />

</p:column>

</p:dataTable>

Filter located at header is a global one applying on all fields, this is implemented by calling client side API method called filter(), important part is to specify the id of the input text as globalFilter which is a reserved identifier for datatable.

In addition to default filtering with generated elements, custom elements can also be used as a filter facet. Example below uses custom filter components in combination with generated elements.

When a custom component is used as a filter facet, filtering needs to be called manually from a preferred event such as onchange="PF('carsTable').filter()". Also defining a converter might be necessary if the value of the filter facet is not defined.

</p:dataTable>

156

PrimeFaces User Guide filterMatchMode defines which built-in filtering algorithm would be used per column, valid values for this attribute are;

- startsWith: Checks if column value starts with the filter value.

- endsWith: Checks if column value ends with the filter value.

- contains: Checks if column value contains the filter value.

- exact: Checks if string representations of column value and filter value are same.

- lt: Checks if column value is less than the filter value.

- lte: Checks if column value is less than or equals the filter value.

- gt: Checks if column value is greater than the filter value.

- gte: Checks if column value is greater than or equals the filter value.

- equals: Checks if column value equals the filter value.

- in: Checks if column value is in the collection of the filter value.

In case the built-in methods do not suffice, custom filtering can be implemented using filterFunction approach.

<p:column filterBy="#{car.price}" filterFunction="#{tableBean.filterByPrice}">

<h:outputText value="#{car.price}">

<f:convertNumber currencySymbol="$" type="currency"/>

</h:outputText>

</p:column>

filterFunction should be a method with three parameters; column value, filter value and locale.

Return value is a boolean, true accepts the value and false rejects it.

public boolean filterByPrice(Object value, Object filter, Locale locale) {

//return true or false

}

Locale is provided as optional in case you need to use a locale aware method like

toLowerCase(Locale locale). Note that String based filters like startsWith, endsWith uses toLowerCase already and dataLocale attribute is used to provide the locale to use when filtering.

Row Selection

There are several ways to select row(s) from datatable. Let’s begin by adding a Car reference for single selection and a Car array for multiple selection to the CarBean to hold the selected data.

public class CarBean { private List<Car> cars; private Car selectedCar; private Car[] selectedCars; public CarBean() { cars = new ArrayList<Car>();

//populate cars

}

//getters and setters

}

Single Selection with a Command Component

This method is implemented with a command component such as commandLink or commandButton. Selected row can be set to a server side instance by passing as a parameter if you are using EL 2.2 or using f:setPropertyActionListener.

157

PrimeFaces User Guide

<p:dataTable var="car" value="#{carBean.cars}">

<p:column>

<p:commandButton value="Select">

<f:setPropertyActionListener value="#{car}" target="#{carBean.selectedCar}" />

</p:commandButton>

</p:column>

...columns

</p:dataTable>

Single Selection with Row Click

Previous method works when the button is clicked, if you’d like to enable selection wherever the row is clicked, use selectionMode option.

<p:dataTable var="car" value="#{carBean.cars}" selectionMode="single" selection="#{carBean.selectedCar}" rowKey="#{car.id}">

...columns

</p:dataTable>

Multiple Selection with Row Click

Multiple row selection is similar to single selection but selection should reference an array or a list of the domain object displayed and user needs to use press modifier key(e.g. ctrl) during selection *.

<p:dataTable var="car" value="#{carBean.cars}" selectionMode="multiple" selection="#{carBean.selectedCars}" rowKey="#{car.id}" >

...columns

</p:dataTable>

Single Selection with RadioButton

Selection a row with a radio button placed on each row is a common case, datatable has built-in support for this method so that you don’t need to deal with h:selectOneRadios and low level bits. In order to enable this feature, define a column with selectionMode set as single.

<p:dataTable var="car" value="#{carBean.cars}" selection="#{carBean.selectedCar}" rowKey="#{car.id}">

<p:column selectionMode="single"/>

...columns

</p:dataTable>

Multiple Selection with Checkboxes

Similar to how radio buttons are enabled, define a selection column with a multiple selectionMode.

DataTable will also provide a selectAll checkbox at column header.

<p:dataTable var="car" value="#{carBean.cars}" selection="#{carBean.selectedCars}" rowKey="#{car.id}" >

<p:column selectionMode="multiple"/>

...columns

</p:dataTable>

158

PrimeFaces User Guide

* Use rowSelectMode option to customize the default behavior on row click of a multiple selection enabled datatable. Default value is "new" that clears previous selections, "add" mode keeps previous selections same as selecting a row with mouse click when metakey is on and

"checkbox" mode allows row selection with checkboxes only.

RowKey

RowKey should a unique identifier from your data model and used by datatable to find the selected rows. You can either define this key by using the rowKey attribute or by binding a data model which implements org.primefaces.model.SelectableDataModel.

Dynamic Columns

Dynamic columns is handy in case you can’t know how many columns to render. Columns component is used to define the columns programmatically. It requires a collection as the value, two iterator variables called var and columnIndexVar.

<p:dataTable var="cars" value="#{tableBean.cars}">

<p:columns value="#{tableBean.columns}" var="column" sortBy="#{column.property}" filterBy="#{column.property}">

<f:facet name="header">

#{column.header}

</f:facet>

<h:outputText value="#{cars[column.property]}" />

</p:columns>

</p:dataTable>

159

PrimeFaces User Guide public class CarBean { private List<ColumnModel> columns = new ArrayList<ColumnModel>(); private List<Car> cars; public CarBean() { populateColumns(); cars = //populate cars;

} public void populateColumns() {

String[] columnKeys = new String[]{"model","year","color"};

for(String columnKey : columnKeys) {

columns.add(new ColumnModel(columnKey.toUpperCase(), columnKey));

}

//getters and setters

public ColumnModel(String header, String property) {

this.header = header;

this.property = property;

}

public String getHeader() {

}

public String getProperty() {

return property;

}

Scrolling

Scrolling makes the header-footer of the table fixed and the body part scrollable. scrollable attribute must be enabled and depending on the scrolling orientation, scrollHeight and/or scrollWidth options must be specified.

<p:dataTable var="car" value="#{bean.data}" scrollable="true" scrollHeight="150">

<p:column />

//columns

</p:dataTable>

Simple scrolling renders all data to client whereas live scrolling is useful to deal with huge data, in this case data is fetched whenever the scrollbar reaches bottom. Set liveScroll to enable this option;

<p:dataTable var="car" value="#{bean.data}" scrollable="true" scrollHeight="150" liveScroll="true">

<p:column />

//columns

</p:dataTable>

Scrolling has 3 modes; x, y and x-y scrolling that are defined by scrollHeight and scrollWidth.

These two scroll attributes can be defined using integer values indicating fixed pixels or percentages relative to the container dimensions.

Frozen Rows

Certain rows can be fixed in a scrollable table by using the frozenRows attribute that defines the number of rows to freeze from the start.

<p:dataTable var="car" value="#{bean.data}" scrollable="true" scrollHeight="150" frozenRows="2">

<p:column />

//columns

</p:dataTable>

Frozen Columns

Specific columns can be fixed while the rest of them remain as scrollable. frozenColumns defines the number of columns to freeze from the start.

162

PrimeFaces User Guide

<p:dataTable var="car" value="#{bean.data}" scrollable="true" scrollWidth="200" frozenColumns="2">

<p:column />

//columns

</p:dataTable>

Expandable Rows

RowToggler and RowExpansion facets are used to implement expandable rows.

<p:dataTable var="car" value="#{carBean.cars}">

<f:facet name="header">

Expand rows to see detailed information

</f:facet>

<p:column>

<p:rowToggler />

</p:column>

//columns

<p:rowExpansion>

//Detailed content of a car

</p:rowExpansion>

</p:dataTable> p:rowToggler component places an expand/collapse icon, clicking on a collapsed row loads expanded content with ajax. If you need to display a row as expanded by default, use expandedRow attribute which is evaluated before rendering of each row so value expressions are supported.

Additionally, rowExpandMode attribute defines if multiple rows can be expanded at the same time or not, valid values are "single" and "multiple" (default).

Editing

Incell editing provides an easy way to display editable data. p:cellEditor is used to define the cell editor of a particular column. There are two types of editing, row and cell. Row editing is the default mode and used by adding a p:rowEditor component as row controls.

163

<p:dataTable var="car" value="#{carBean.cars}" editable="true">

<f:facet name="header">

In-Cell Editing

</f:facet>

<p:column headerText="Model">

<p:cellEditor>

<f:facet name="output">

<h:outputText value="#{car.model}" />

</f:facet>

<f:facet name="input">

<h:inputText value="#{car.model}"/>

</f:facet>

</p:cellEditor>

</p:column>

//more columns with cell editors

<p:column>

<p:rowEditor />

</p:column>

</p:dataTable>

PrimeFaces User Guide

When pencil icon is clicked, row is displayed in editable mode meaning input facets are displayed and output facets are hidden. Clicking tick icon only saves that particular row and cancel icon reverts the changes, both options are implemented with ajax interaction.

Another option for incell editing is cell editing, in this mode a cell switches to edit mode when it is clicked, losing focus triggers an ajax event to save the change value.

Lazy Loading

Lazy Loading is an approach to deal with huge datasets efficiently, regular ajax based pagination works by rendering only a particular page but still requires all data to be loaded into memory. Lazy loading datatable renders a particular page similarly but also only loads the page data into memory not the whole dataset. In order to implement this, you’d n e e d t o b i n d a

org.primefaces.model.LazyDataModel as the value and implement load method and enable lazy option. Also it is required to implement getRowData and getRowKey if you have selection enabled.

164

PrimeFaces User Guide

<p:dataTable var="car" value="#{carBean.model}" paginator="true" rows="10" lazy="true">

//columns

</p:dataTable> public class CarBean { private LazyDataModel model; public CarBean() { model = new LazyDataModel() {

@Override public void load(int first, int pageSize, String sortField,

SortOrder sortOrder, Map<String,Object> filters) {

//load physical data

}

}; int totalRowCount = //logical row count based on a count query model.setRowCount(totalRowCount);

} public LazyDataModel getModel() { return model;

}

DataTable calls your load implementation whenever a paging, sorting or filtering occurs with following parameters;

• first: Offset of first data to start from

• pageSize: Number of data to load

• sortField: Name of sort field

• sortOrder: SortOrder enum.

• filter: Filter map with field name as key (e.g. "model" for filterBy="#{car.model}") and value.

In addition to load method, totalRowCount needs to be provided so that paginator can display itself according to the logical number of rows to display.

It is suggested to use field attribute of column component to define the field names passed as sortField and filterFields, otherwise these fields would be tried to get extracted from the value expression which is not possible in cases like composite components.

Sticky Header

Sticky Header feature makes the datatable header visible on page scrolling.

<p:dataTable var="car" value="#{carBean.model}" stickyHeader="true">

//columns

</p:dataTable>

On page load, column chooser finds all columns of datatable and generates the ui. If you'd like some of the columns to be ignored, set toggleable option of a column as false. Optional toggle ajax behavior is provided by columnChooser component to listen to toggle events at server side. Listener of this behavior gets an org.primefaces.event.ToggleEvent as a parameter that gives the visibility and index of the column being toggled.

Reordering Rows

Rows of the table can be reordered using drag&drop. Set draggableRows attribute to true to enable this feature.

Optional rowReorder ajax behavior is provided to listen to reorder events at server side. Listener of this behavior gets an org.primefaces.event.ReorderEvent as a parameter that gives the past and current index of the row being moved.

3.33 DefaultCommand

Which command to submit the form with when enter key is pressed a common problem in web apps not just specific to JSF. Browsers tend to behave differently as there doesn’t seem to be a standard and even if a standard exists, IE probably will not care about it. There are some ugly workarounds like placing a hidden button and writing javascript for every form in your app. DefaultCommand solves this problem by normalizing the command(e.g. button or link) to submit the form with on enter key press.

Boolean Dialog size might exceeed viewport if content is bigger than viewport in terms of height. fitViewport option automatically adjusts height to fit dialog within the viewport.

Getting started with the Dialog

Dialog is a panel component containing other components, note that by default dialog is not visible.

<p:dialog>

<h:outputText value="Resistance to PrimeFaces is Futile!" />

//Other content

</p:dialog>

Show and Hide

Showing and hiding the dialog is easy using the client side api.

177

PrimeFaces User Guide

<p:dialog header="Header Text" widgetVar="dlg">//Content</p:dialog>

<p:commandButton value="Show" type="button" onclick="PF('dlg').show()" />

<p:commandButton value="Hide" type="button" onclick="PF('dlg').hide()" />

Effects

There are various effect options to be used when displaying and closing the dialog. Use showEffect and hideEffect options to apply these effects; blind, bounce, clip, drop, explode, fade, fold, highlight, puff, pulsate, scale, shake, size, slide and transfer.

<p:dialog showEffect="fade" hideEffect="explode" ...>

//...

</p:dialog>

Position

By default dialog is positioned at center of the viewport and position option is used to change the location of the dialog. Possible values are;

• Single string value like ‘center’, ‘left’, ‘right’, ‘top’, ‘bottom’ representing the position within viewport.

•

Comma separated x and y coordinate values like 200, 500

• Comma separated position values like ‘top’,‘right’. (Use single quotes when using a combination)

Some examples are described below;

<p:dialog position="top" ...>

<p:dialog position="left,top" ...>

<p:dialog position="200,50" ...>

Focus

Dialog applies focus on first visible input on show by default which is useful for user friendliness however in some cases this is not desirable. Assume the first input is a popup calendar and opening the dialog shows a popup calendar. To customize default focus behavior, use focus attribute.

Ajax Behavior Events

close event is one of the ajax behavior events provided by dialog that is fired when the dialog is hidden. If there is a listener defined it’ll be executed by passing an instance of

org.primefaces.event.CloseEvent.

Example below adds a FacesMessage when dialog is closed and updates the messages component to display the added message.

178

PrimeFaces User Guide

<p:dialog>

<p:ajax event="close" listener="#{dialogBean.handleClose}" update="msg" />

//Content

</p:dialog>

<p:messages id="msg" /> public class DialogBean { public void handleClose(CloseEvent event) {

//Add facesmessage

}

3 other ajax behavior events are maximize, minimize, move that are invoked when dialog is maximized, minimized and moved respectively.

Client Side Callbacks

Similar to close listener, onShow and onHide are handy callbacks for client side in case you need to execute custom javascript.

<p:dialog onShow="alert(‘Visible’)" onHide="alert(‘Hidden’)">

//Content

</p:dialog>

Client Side API

Widget: PrimeFaces.widget.Dialog show()

PrimeFaces User Guide

As skinning style classes are global, see the main theming section for more information.

Tips

• Use appendTo with care as the page definition and html dom would be different, for example if dialog is inside an h:form component and appendToBody is enabled, on the browser dialog would be outside of form and may cause unexpected results. In this case, nest a form inside a dialog.

• Do not place dialog inside tables, containers likes divs with relative positioning or with nonvisible overflow defined, in cases like these functionality might be broken. This is not a limitation but a result of DOM model. For example dialog inside a layout unit, tabview, accordion are a couple of examples. Same applies to confirmDialog as well.

ZIndex to apply during dragging.

Specifies a handle for dragging.

Defines the opacity of the helper during dragging.

In stack mode, draggable overlap is controlled automatically using the provided selector, dragged item always overlays other draggables.

Dragging happens in every x and y pixels.

Scope key to match draggables and droppables.

CSS cursor to display in dragging.

Id of the dashboard to connect with.

A search expression to define which element to append the draggable helper to.

Getting started with Draggable

Any component can be enhanced with draggable behavior, basically this is achieved by defining the id of component using the for attribute of draggable.

<p:panel id="pnl" header="Draggable Panel">

<h:outputText value="This is actually a regular panel" />

</p:panel>

<p:draggable for="pnl"/>

If you omit the for attribute, parent component will be selected as the draggable target.

<h:graphicImage id="campnou" value="/images/campnou.jpg">

<p:draggable />

</h:graphicImage>

Handle

By default any point in dragged component can be used as handle, if you need a specific handle, you can define it with handle option. Following panel is dragged using it’s header only.

<p:panel id="pnl" header="Draggable Panel">

<h:outputText value="I can only be dragged using my header" />

</p:panel>

<p:draggable for="pnl" handle="div.ui-panel-titlebar"/>

182

PrimeFaces User Guide

Drag Axis

Dragging can be limited to either horizontally or vertically.

<p:panel id="pnl" header="Draggable Panel">

<h:outputText value="I am dragged on an axis only" />

</p:panel>

<p:draggable for="pnl" axis="x or y"/>

Clone

By default, actual component is used as the drag indicator, if you need to keep the component at it’s original location, use a clone helper.

<p:panel id="pnl" header="Draggable Panel">

<h:outputText value="I am cloned" />

</p:panel>

<p:draggable for="pnl" helper="clone"/>

Revert

When a draggable is not dropped onto a matching droppable, revert option enables the component to move back to it’s original position with an animation.

<p:panel id="pnl" header="Draggable Panel">

<h:outputText value="I will be reverted back to my original position" />

</p:panel>

<p:draggable for="pnl" revert="true"/>

Opacity

During dragging, opacity option can be used to give visual feedback, helper of following panel’s opacity is reduced in dragging.

<p:panel id="pnl" header="Draggable Panel">

<h:outputText value="My opacity is lower during dragging" />

</p:panel>

<p:draggable for="pnl" opacity="0.5"/>

Grid

Defining a grid enables dragging in specific pixels. This value takes a comma separated dimensions in x,y format.

<p:panel id="pnl" header="Draggable Panel">

<h:outputText value="I am dragged in grid mode" />

</p:panel>

<p:draggable for="pnl" grid="20,40"/>

183

PrimeFaces User Guide

Containment

A draggable can be restricted to a certain section on page, following draggable cannot go outside of it’s parent.

<p:outputPanel layout="block" style="width:400px;height:200px;">

<p:panel id="conpnl" header="Restricted">

<h:outputText value="I am restricted to my parent's boundaries" />

185

PrimeFaces User Guide

Getting Started with Droppable

Usage of droppable is very similar to draggable, droppable behavior can be added to any component specified with the for attribute.

<p:outputPanel id="slot" styleClass="slot" />

<p:droppable for="slot" /> slot styleClass represents a small rectangle.

.slot { background:#FF9900; width:64px; height:96px; display:block;

}

</style>

If for attribute is omitted, parent component becomes droppable.

<p:outputPanel id="slot" styleClass="slot">

<p:droppable />

</p:outputPanel>

Ajax Behavior Events

drop is the only and default ajax behavior event provided by droppable that is processed when a valid draggable is dropped. In case you define a listener it’ll be executed by passing an

org.primefaces.event.DragDrop event instance parameter holding information about the dragged and dropped components.

Following example shows how to enable draggable images to be dropped on droppables.

<p:graphicImage id="messi" value="barca/messi_thumb.jpg" />

<p:draggable for="messi"/>

<p:outputPanel id="zone" styleClass="slot" />

<p:droppable for="zone">

<p:ajax listener="#{ddController.onDrop}" />

</p:droppable> public void onDrop(DragDropEvent ddEvent) {

String draggedId = ddEvent.getDragId();

String droppedId = ddEvent.getDropId();

Object data = ddEvent.getData();

}

//Client id of dragged component

//Client id of dropped component

//Model object of a datasource

186

PrimeFaces User Guide

onDrop

onDrop is a client side callback that is invoked when a draggable is dropped, it gets two parameters event and ui object holding information about the drag drop event.

<p:outputPanel id="zone" styleClass="slot" />

<p:droppable for="zone" onDrop="handleDrop"/> function handleDrop(event, ui) { var draggable = ui.draggable, helper = ui.helper, position = ui.position, offset = ui.offset;

}

//draggable element, a jQuery object

//helper element of draggable, a jQuery object

//position of draggable helper

//absolute position of draggable helper

DataSource

Droppable has special care for data elements that extend from UIData(e.g. datatable, datagrid), in order to connect a droppable to accept data from a data component define datasource option as the id of the data component. Example below show how to drag data from datagrid and drop onto a droppable to implement a dragdrop based selection. Dropped cars are displayed with a datatable.

public class TableBean { private List<Car> availableCars; private List<Car> droppedCars; public TableBean() { availableCars = //populate data

}

//getters and setters public void onCarDrop(DragDropEvent event) {

Car car = ((Car) ddEvent.getData()); droppedCars.add(car); availableCars.remove(car);

}

PrimeFaces User Guide

Tolerance

There are four different tolerance modes that define the way of accepting a draggable.

fit intersect pointer touch

Mode Description

draggable should overlap the droppable entirely draggable should overlap the droppable at least 50% pointer of mouse should overlap the droppable droppable should overlap the droppable at any amount

Acceptance

You can limit which draggables can be dropped onto droppables using scope attribute which a draggable also has. Following example has two images, only first image can be accepted by droppable.

<p:graphicImage id="messi" value="barca/messi_thumb.jpg" />

<p:draggable for="messi" scope="forward"/>

<p:graphicImage id="xavi" value="barca/xavi_thumb.jpg" />

<p:draggable for="xavi" scope="midfield"/>

<p:outputPanel id="forwardsonly" styleClass="slot" scope="forward" />

<p:droppable for="forwardsonly" />

Skinning

hoverStyleClass and activeStyleClass attributes are used to change the style of the droppable when interacting with a draggable.

Dom event to attach the event that executes the animation

Specifies the name of the animation

Component that is animated

Speed of the animation in ms

Time to wait until running the effect.

Getting started with Effect

Effect component needs a trigger and target which is effect’s parent by default. In example below clicking outputText (trigger) will run the pulsate effect on outputText(target) itself.

196

PrimeFaces User Guide

<h:outputText value="#{bean.value}">

<p:effect type="pulsate" event="click" />

</h:outputText>

Effect Target

There may be cases where you want to display an effect on another target on the same page while keeping the parent as the trigger. Use for option to specify a target.

<h:outputLink id="lnk" value="#">

<h:outputText value="Show the Barca Temple" />

<p:effect type="appear" event="click" for="img" />

</h:outputLink>

<p:graphicImage id="img" value="/ui/barca/campnou.jpg" style="display:none"/>

With this setting, outputLink becomes the trigger for the effect on graphicImage. When the link is clicked, initially hidden graphicImage comes up with a fade effect.

Note: It’s important for components that have the effect component as a child to have an assigned id because some components do not render their clientId’s if you don’t give them an id explicitly.

List of Effects

Following is the list of effects;

• blind

• clip

• drop

• explode

• fold

• puff

• slide

• scale

• bounce

• highlight

• pulsate

• shake

• size

• transfer

197

PrimeFaces User Guide

Effect Configuration

Each effect has different parameters for animation like colors, duration and more. In order to change the configuration of the animation, provide these parameters with the f:param tag.

<h:outputText value="#{bean.value}">

<p:effect type="scale" event="mouseover">

<f:param name="percent" value="90"/>

</p:effect>

</h:outputText>

It’s important to provide string options with single quotes.

<h:outputText value="#{bean.value}">

<p:effect type="blind" event="click">

<f:param name="direction" value="'horizontal'" />

</p:effect>

</h:outputText>

For the full list of configuration parameters for each effect, please see the jquery documentation; http://docs.jquery.com/UI/Effects

Effect on Load

Effects can also be applied to any JSF component when page is loaded for the first time or after an ajax request is completed by using load as the event name. Following example animates messages with pulsate effect after ajax request completes.

<p:messages id="messages">

<p:effect type="pulsate" event="load" delay=”500”>

<f:param name="mode" value="'show'" />

</p:effect>

</p:messages>

<p:commandButton value="Save" actionListener="#{bean.action}" update="messages"/>

PrimeFaces User Guide

Getting started with Fieldset

Fieldset is used as a container component for its children.

<p:fieldset legend="Simple Fieldset">

<h:panelGrid column="2">

<p:graphicImage value="/images/godfather/1.jpg" />

<h:outputText value="The story begins as Don Vito Corleone ..." />

</h:panelGrid>

</p:fieldset>

Legend

Legend can be defined in two ways, with legend attribute as in example above or using legend facet. Use facet way if you need to place custom html other than simple text.

<p:fieldset>

<f:facet name="legend">

</f:facet>

//content

</p:fieldset>

When both legend attribute and legend facet are present, facet is chosen.

Toggleable Content

Clicking on fieldset legend can toggle contents, this is handy to use space efficiently in a layout. Set toggleable to true to enable this feature.

<p:fieldset legend="Toggleable Fieldset" toggleable="true">

<h:panelGrid column="2">

<p:graphicImage value="/images/godfather/2.jpg" />

<h:outputText value="Francis Ford Coppolas’ legendary ..." />

</h:panelGrid>

</p:fieldset>

Ajax Behavior Events

toggle is the default and only ajax behavior event provided by fieldset that is processed when the content is toggled. In case you have a listener defined, it will be invoked by passing an instance of

org.primefaces.event.ToggleEvent.

201

PrimeFaces User Guide

Here is an example that adds a facesmessage and updates growl component when fieldset is toggled.

<p:growld id="messages" />

<p:fieldset legend="Toggleable Fieldset" toggleable="true"

<p:ajax listener="#{bean.onToggle}" update="messages">

//content

</p:fieldset> public void onToggle(ToggleEvent event) {

Visibility visibility = event.getVisibility();

FacesMessage msg = new FacesMessage(); msg.setSummary("Fieldset " + event.getId() + " toggled"); msg.setDetail("Visibility: " + visibility);

FacesContext.getCurrentInstance().addMessage(null, msg);

}

Client Side API

Widget: PrimeFaces.widget.Fieldset toggle()

Tips

• A collapsed fieldset will remain collapsed after a postback since fieldset keeps its toggle state internally, you don’t need to manage this using toggleListener and collapsed option.

3.41 FileDownload

The legacy way to present dynamic binary data to the client is to write a servlet or a filter and stream the binary data. FileDownload presents an easier way to do the same.

StreamedContent

Description

A streamed content instance

Specifies display mode.

Getting started with FileDownload

A user command action is required to trigger the filedownload process. FileDownload can be attached to any command component like a commandButton or commandLink. The value of the

FileDownload must be an org.primefaces.model.StreamedContent instance. We suggest using the built-in DefaultStreamedContent implementation. First parameter of the constructor is the binary stream, second is the mimeType and the third parameter is the name of the file.

public class FileBean {

private StreamedContent file;

public FileDownloadController() {

InputStream stream = this.getClass().getResourceAsStream("yourfile.pdf");

file = new DefaultStreamedContent(stream, "application/pdf",

"downloaded_file.pdf");

} public StreamedContent getFile() { return this.file;

}

This streamed content should be bound to the value of the fileDownload.

<h:commandButton value="Download">

<p:fileDownload value="#{fileBean.file}" />

</h:commandButton>

Similarly a more graphical presentation would be to use a commandlink with an image.

203

PrimeFaces User Guide

<h:commandLink value="Download">

<p:fileDownload value="#{fileBean.file}"/>

<h:graphicImage value="pdficon.gif" />

</h:commandLink>

If you’d like to use PrimeFaces commandButton and commandLink, disable ajax option as fileDownload requires a full page refresh to present the file.

<p:commandButton value="Download" ajax="false">

<p:fileDownload value="#{fileBean.file}" />

</p:commandButton>

<p:commandLink value="Download" ajax="false">

<p:fileDownload value="#{fileBean.file}"/>

<h:graphicImage value="pdficon.gif" />

</p:commandLink>

ContentDisposition

By default, content is displayed as an attachment with a download dialog box, another alternative is the inline mode, in this case browser will try to open the file internally without a prompt. Note that content disposition is not part of the http standard although it is widely implemented.

Monitor Status

As fileDownload process is non-ajax, ajaxStatus cannot apply. Still PrimeFaces provides a feature to monitor file downloads via client side monitorDownload(startFunction, endFunction) method.

Example below displays a modal dialog when dowload begins and hides it on complete.

PF('statusDialog').show();

} function hideStatus() {

PF('statusDialog').hide();

}

</script>

<h:form>

<p:dialog modal="true" widgetVar="statusDialog" header="Status" draggable="false" closable="false">

<p:graphicImage value="/design/ajaxloadingbar.gif" />

</p:dialog>

<p:commandButton value="Download" ajax="false" onclick="PrimeFaces.monitorDownload(showStatus, hideStatus)">

<p:fileDownload value="#{fileDownloadController.file}"/>

</p:commandButton>

</h:form>

Cookies must be enabled for monitoring.

Getting started with FileUpload

FileUpload engine on the server side can either be servlet 3.0 or commons fileupload. PrimeFaces selects the most appropriate uploader engine by detection and it is possible to force one or the other usign an optional configuration param.

<context-param>

<param-name>primefaces.UPLOADER</param-name>

<param-value>auto|native|commons</param-value>

</context-param>

auto: This is the default mode and PrimeFaces tries to detect the best method by checking the runtime environment, if JSF runtime is at least 2.2 native uploader is selected, otherwise commons.

native: Native mode uses servlet 3.x Part API to upload the files and if JSF runtime is less than 2.2

and exception is being thrown.

commons: This option chooses commons fileupload regardless of the environment, advantage of this option is that it works even on a Servlet 2.5 environment.

If you have decided to choose commons fileupload, it requires the following filter configration in your web deployment descriptior.

Note that the servlet-name should match the configured name of the JSF servlet which is Faces

Simple File Upload

Simple file upload mode works in legacy mode with a file input whose value should be an

UploadedFile instance. Ajax uploads are not supported in simple upload.

<h:form enctype="multipart/form-data">

<p:fileUpload value="#{fileBean.file}" mode="simple" />

<p:commandButton value="Submit" ajax="false"/>

</h:form> import org.primefaces.model.UploadedFile;

public class FileBean { private UploadedFile file;

//getter-setter

}

Advanced File Upload

FileUploadListener is the way to access the uploaded files in this mode, when a file is uploaded defined fileUploadListener is processed with a FileUploadEvent as the parameter.

<p:fileUpload fileUploadListener="#{fileBean.handleFileUpload}" /> public class FileBean { public void handleFileUpload(FileUploadEvent event) {

UploadedFile file = event.getFile();

//application code

}

208

PrimeFaces User Guide

Multiple Uploads

Multiple uploads can be enabled using the multiple attribute so that multiple files can be selected from browser dialog. Multiple uploads are not supported in legacy browsers. Note that multiple mode is for selection only, it does not send all files in one request. FileUpload component always uses a new request for each file.

<p:fileUpload fileUploadListener="#{fileBean.handleFileUpload}" multiple="true" />

Auto Upload

Default behavior requires users to trigger the upload process, you can change this way by setting auto to true. Auto uploads are triggered as soon as files are selected from the dialog.

<p:fileUpload fileUploadListener="#{fileBean.handleFileUpload}" auto="true" />

Partial Page Update

After the fileUpload process completes you can use the PrimeFaces PPR to update any component on the page. FileUpload is equipped with the update attribute for this purpose. Following example displays a "File Uploaded" message using the growl component after file upload.

<p:fileUpload fileUploadListener="#{fileBean.handleFileUpload}" update="msg" />

<p:growl id="msg" /> public class FileBean { public void handleFileUpload(FileUploadEvent event) {

//add facesmessage to display with growl

//application code

}

File Filters

Users can be restricted to only select the file types you’ve configured, example below demonstrates how to accept images only.

<p:fileUpload fileUploadListener="#{fileBean.handleFileUpload}" allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>

Size Limit

Most of the time you might need to restrict the file upload size for a file, this is as simple as setting the sizeLimit configuration. Following fileUpload limits the size to 1000 bytes for each file.

<p:fileUpload fileUploadListener="#{fileBean.handleFileUpload}" sizeLimit="1000" />

209

PrimeFaces User Guide

File Limit

FileLimit restricts the number of maximum files that can be uploaded.

<p:fileUpload fileUploadListener="#{fileBean.handleFileUpload}" fileLimit="3" />

Validation Messages

invalidFileMessage, invalidSizeMessage and fileLimitMessage options are provided to display validation messages to the users. Similar to the FacesMessage message API, these message define the summary part, the detail part is retrieved from the messageTemplate option where default value is “{name} {size}”.

Skinning

FileUpload resides in a container element which style and styleClass options apply. As skinning style classes are global, see the main theming section for more information. Following is the list of structural style classes

Class

.ui-fileupload

.fileupload-buttonbar

.fileinput-button

.ui-fileupload start

.ui-fileupload cancel fileupload-content

Main container element

Button bar.

Browse button.

Upload button.

Cancel button.

Content container.

Applies

Browser Compatibility

Advanced uploader is implemented with HTML5 and provides far more features compared to single version. For legacy browsers that do not support HMTL5 features like canvas or file api, fileupload uses graceful degradation so that iframe is used for transport, detailed file information is not shown and a gif animation is displayed instead of progress bar. It is suggested to offer simple uploader as a fallback.

Filter Configuration

Filter configuration is required if you are using commons uploader only. Two configuration options exist, threshold size and temporary file upload location.

Parameter Name

thresholdSize uploadDirectory

Description

Maximum file size in bytes to keep uploaded files in memory. If a file exceeds this limit, it’ll be temporarily written to disk.

Disk repository path to keep temporary files that exceeds the threshold size.

By default it is System.getProperty("java.io.tmpdir")

210

PrimeFaces User Guide

An example configuration below defined thresholdSize to be 50kb and uploads to users temporary folder.

<filter-name>PrimeFaces FileUpload Filter</filter-name>

<filter-class> org.primefaces.webapp.filter.FileUploadFilter

</filter-class>

<init-param>

<param-name>thresholdSize</param-name>

<param-value>51200</param-value>

</init-param>

<init-param>

<param-name>uploadDirectory</param-name>

<param-value>/Users/primefaces/temp</param-value>

</init-param>

</filter>

Note that uploadDirectory is used internally, you always need to implement the logic to save the file contents yourself in your backing bean.

String

Description

Unique identifier of the component

Boolean value to specify the rendering of the component, when set to false component will not be rendered.

An el expression that maps to a server side

UIComponent instance in a backing bean

Specifies the exact component to set focus

The root component to start first input search.

Minimum severity level to be used when finding the first invalid component

Getting started with Focus

By default focus will find the first enabled and visible input component on page and apply focus.

Input component can be any element such as input, textarea and select.

<p:focus />

<p:inputText ... />

<h:inputText ... />

<h:selectOneMenu ... />

Following is a simple example;

212

PrimeFaces User Guide

<h:form>

<p:panel id="panel" header="Register">

<p:focus />

<p:messages />

<h:panelGrid columns="3">

<h:outputLabel for="firstname" value="Firstname: *" />

<h:inputText id="firstname" value="#{pprBean.firstname}" required="true" label="Firstname" />

<p:message for="firstname" />

<h:outputLabel for="surname" value="Surname: *" />

<h:inputText id="surname" value="#{pprBean.surname}" required="true" label="Surname"/>

<p:message for="surname" />

</h:panelGrid>

<p:commandButton value="Submit" update="panel" actionListener="#{pprBean.savePerson}" />

</p:panel>

</h:form>

When this page initially opens up, input text with id "firstname" will receive focus as it is the first input component.

Validation Aware

Another useful feature of focus is that when validations fail, first invalid component will receive a focus. So in previous example if firstname field is valid but surname field has no input, a validation error will be raised for surname, in this case focus will be set on surname field implicitly. Note that for this feature to work on ajax requests, you need to update p:focus component as well.

Explicit Focus

Additionally, using for attribute focus can be set explicitly on an input component which is useful when using a dialog.

<p:focus for="text"/>

<h:inputText id="text" value="{bean.value}" />

Object An el expression that maps to a server side UIComponent instance in a backing bean

Boolean Updates the fragment automatically.

Getting started with Fragment

In the following case, required input field outside the fragment is ignored and only the contents of the fragment are processed-updated automatically on button click since button is inside the fragment. Fragment makes it easy to define partial ajax process and update without explicitly defining component identifiers.

214

PrimeFaces User Guide

<h:form>

<h:panelGrid columns="2">

<p:outputLabel for="ign" value="Required:" />

<p:inputText id="ign" required="true" />

</h:panelGrid>

<p:fragment autoUpdate="true">

<h:panelGrid columns="4" cellpadding="5">

<h:outputLabel for="name" value="Name:" />

<h:outputText value="#{pprBean.firstname}" />

</h:panelGrid>

</p:fragment>

<p:inputText id="name" value="#{pprBean.firstname}" />

<p:commandButton value="Submit"/>

</h:form>

AutoUpdate has different notion compared to autoUpdate of message, growl and outputPanel. The fragment is updated automatically after an ajax request if the source is a descendant. In other mentioned components, there is no such restriction as they are updated for every ajax request regardless of the source.

Getting Started with Galleria

Images to displayed are defined as children of galleria;

<p:galleria effect="slide" effectDuration="1000">

<p:graphicImage value="/images/image1.jpg" title="image1" alt="image1 desc" />

<p:graphicImage value="/images/image2.jpg" title="image1" alt=" image2 desc" />

<p:graphicImage value="/images/image3.jpg" title="image1" alt=" image3 desc" />

<p:graphicImage value="/images/image4.jpg" title="image1" alt=" image4 desc" />

</p:galleria>

Galleria displays the details of an image using an overlay which is displayed by clicking the information icon. Title of this popup is retrieved from the image title attribute and description from

alt attribute so it is suggested to provide these attributes as well.

Dynamic Collection

Most of the time, you would need to display a dynamic set of images rather than defining each image declaratively. For this you can use built-in data iteration feature.

<p:galleria value="#{galleriaBean.images}" var="image" >

<p:graphicImage value="#{image.path}" title="#{image.title}" alt="#{image.description}" />

</p:galleria>

Effects

There are various effect options to be used in transitions; blind, bounce, clip, drop, explode, fade, fold, highlight, puff, pulsate, scale, shake, size, slide and transfer.

By default animation takes 500 milliseconds, use effectSpeed option to tune this.

Getting started with GMap

First thing to do is placing V3 of the Google Maps API that the GMap is based on. Ideal location is the head section of your page.

As Google Maps api states, mandatory sensor parameter is used to specify if your application requires a sensor like GPS locator. Four options are required to place a gmap on a page, these are center, zoom, type and style.

<p:gmap center="41.381542, 2.122893" zoom="15" type="hybrid" style="width:600px;height:400px" />

center: Center of the map in lat, lng format

zoom: Zoom level of the map

type: Type of map, valid values are, "hybrid", "satellite", "hybrid" and "terrain".

style: Dimensions of the map.

Getting started with GraphicImage

GraphicImage requires an org.primefaces.model.StreamedContent content as it’s value for dynamic images. StreamedContent is an interface and PrimeFaces provides a built-in implementation called

DefaultStreamedContent. Following examples loads an image from the classpath.

<p:graphicImage value="#{imageBean.image}" /> public class ImageBean { private StreamedContent image; public DynamicImageController() {

InputStream stream = this.getClass().getResourceAsStream("barcalogo.jpg");

image = new DefaultStreamedContent(stream, "image/jpeg");

} public StreamedContent getImage() { return this.image;

}

DefaultStreamedContent gets an inputstream as the first parameter and mime type as the second.

In a real life application, you can create the inputstream after reading the image from the database.

For example java.sql.ResultsSet API has the getBinaryStream() method to read blob files stored in database.

Displaying Charts with JFreeChart

See static images section at chart component for a sample usage of graphicImage with jFreeChart.

Displaying a Barcode

Similar to the chart example, a barcode can be generated as well. This sample uses barbecue project for the barcode API.

<p:graphicImage value="#{backingBean.barcode}" /> public class BarcodeBean { private StreamedContent barcode; public BackingBean() { try {

File barcodeFile = new File("dynamicbarcode");

BarcodeImageHandler.saveJPEG(

BarcodeFactory.createCode128("PRIMEFACES"), barcodeFile); barcode = new DefaultStreamedContent( new FileInputStream(barcodeFile), "image/jpeg");

} catch (Exception e) { e.printStackTrace();

}

} public BarcodeBean getBarcode() { return this.barcode;

}

Displaying Regular Images

As GraphicImage extends standard graphicImage component, it can also display regular non dynamic images just like standard graphicImage component using name and optional library.

<p:graphicImage name="barcalogo.jpg" library="yourapp" />

How It Works

Dynamic image display works as follows;

• Dynamic image encryps its value expression string to generate a key.

• This key is appended to the image url that points to JSF resource handler.

• Custom PrimeFaces ResourceHandler gets the key from the url, decrypts the expression string to something like #{bean.streamedContentValue}, evaluates it to get the instance of

StreamedContent from bean and streams contents to client.

233

PrimeFaces User Guide

As a result there will be 2 requests to display an image, first browser will make a request to load the page and then another one to the dynamic image url that points to JSF resource handler. Please note that you cannot use viewscope beans as they are not available in resource loading request.

Passing Parameters and Data Iteration

You can pass request parameters to the graphicImage via f:param tags, as a result the actual request rendering the image can have access to these values. This is extremely handy to display dynamic images if your image is in a data iteration component like datatable or ui:repeat.

StreamedContent

There are two StreamedContent implementations out of the box; DefaultStreamedContent is not uses an InputStream and not serializable whereas the serializable ByteArrayContent uses a byte array.

Defines whether html would be escaped or not.

Comma separated list of severities to display only.

Getting Started with Growl

Growl usage is similar to standard h:messages component. Simply place growl anywhere on your page, since messages are displayed as an overlay, the location of growl in JSF page does not matter.

<p:growl />

Lifetime of messages

By default each message will be displayed for 6000 ms and then hidden. A message can be made sticky meaning it’ll never be hidden automatically.

<p:growl sticky="true" />

If growl is not working in sticky mode, it’s also possible to tune the duration of displaying messages. Following growl will display the messages for 5 seconds and then fade-out.

<p:growl life="5000" />

Growl with Ajax Updates

If you need to display messages with growl after an ajax request you just need to update it. Note that if you enable autoUpdate, growl will be updated automatically with each ajax request anyway.

<p:growl id="messages"/>

<p:commandButton value="Submit" update="messages" />

Positioning

Growl is positioned at top right corner by default, position can be controlled with a CSS selector called ui-growl. With the below setting growl will be located at top left corner.

.ui-growl { left:20px;

}

238

PrimeFaces User Guide

Targetable Messages

There may be times where you need to target one or more messages to a specific message component, for example suppose you have growl and messages on same page and you need to display some messages on growl and some on messages. Use for attribute to associate messages with specific components.

<p:messages for="somekey" />

<p:growl for="anotherkey" />

FacesContext context = FacesContext.getCurrentInstance();

context.addMessage("somekey", facesMessage1);

context.addMessage("somekey", facesMessage2);

context.addMessage("anotherkey", facesMessage3);

In sample above, messages will display first and second message and growl will only display the

3rd message.

Severity Levels

Using severity attribute, you can define which severities can be displayed by the component. For instance, you can configure growl to only display infos and warnings.

<p:growl severity="info,warn" />

Escaping

Growl escapes html content in messages, in case you need to display html via growl set escape option to false.

<p:growl escape="false" />

Javascript handler to execute when ajax request is completed.

Javascript handler to execute when ajax request succeeds.

Javascript handler to execute when ajax request fails.

Global ajax requests are listened by ajaxStatus component, setting global to false will not trigger ajaxStatus.

If less than delay milliseconds elapses between calls to request() only the most recent one is sent and all other requests are discarded. If this option is not specified, or if the value of delay is the literal string 'none' without the quotes, no delay is used.

Enables serialization of values belonging to the partially processed components only.

If true, local values of input components to be updated within the ajax request would be reset.

If true, components which autoUpdate="true" will not be updated for this request. If not specified, or the value is false, no such indication is made.

Timeout for the ajax request in milliseconds.

Getting Started with HotKey

HotKey is used in two ways, either on client side with the event handler or with ajax support.

Simplest example would be;

<p:hotkey bind="a" handler="alert(‘Pressed a’);" />

When this hotkey is on page, pressing the a key will alert the ‘Pressed key a’ text.

Key combinations

Most of the time you’d need key combinations rather than a single key.

<p:hotkey bind="ctrl+s" handler="alert(‘Pressed ctrl+s’);" />

<p:hotkey bind="ctrl+shift+s" handler="alert(‘Pressed ctrl+shift+s’)" />

Integration

Here’s an example demonstrating how to integrate hotkeys with a client side api. Using left and right keys will switch the images displayed via the p:imageSwitch component.

242

PrimeFaces User Guide

<p:hotkey bind="left" handler="PF('switcher').previous();" />

<p:hotkey bind="right" handler="PF('switcher').next();" />

<p:imageSwitch widgetVar="switcher">

//content

</p:imageSwitch>

Ajax Support

Ajax is a built-in feature of hotKeys meaning you can do ajax calls with key combinations.

Following form can be submitted with the ctrl+shift+s combination.

<h:form>

<p:hotkey bind="ctrl+shift+s" update="display" />

<h:panelGrid columns="2">

<h:outputLabel for="name" value="Name:" />

<h:inputText id="name" value="#{bean.name}" />

</h:panelGrid>

<h:outputText id="display" value="Hello: #{bean.firstname}" />

</h:form>

Note that hotkey will not be triggered if there is a focused input on page.

Getting started with the ImageCropper

ImageCropper is an input component and image to be cropped is provided via the image attribute.

The cropped area of the original image is used to create a new image, this new image can be accessed on the backing bean by setting the value attribute of the image cropper. Assuming the image is at %WEBAPP_ROOT%/campnou.jpg

<p:imageCropper value="#{cropper.croppedImage}" image="/campnou.jpg" /> public class Cropper { private CroppedImage croppedImage;

//getter and setter

}

org.primefaces.model.CroppedImage belongs a PrimeFaces API and contains handy information about the crop process. Following table describes CroppedImage properties.

External Images

ImageCropper has the ability to crop external images as well.

<p:imageCropper value="#{cropper.croppedImage}" image= " ">

</p:imageCropper>

Context Relative Path

For local images, ImageCropper always requires the image path to be context relative. So to accomplish this simply just add slash ("/path/to/image.png") and imagecropper will recognize it at

%WEBAPP_ROOT%/path/to/image.png. Action url relative local images are not supported.

Initial Coordinates

By default, user action is necessary to initiate the cropper area on an image, you can specify an initial area to display on page load using initialCoords option in x,y,w,h format.

<p:imageCropper value="#{cropper.croppedImage}" image="/campnou.jpg" initialCoords="225,75,300,125"/>

Boundaries

minSize and maxSize attributes are control to limit the size of the area to crop.

<p:imageCropper value="#{cropper.croppedImage}" image="/campnou.jpg" minSize="50,100" maxSize="150,200"/>

Saving Images

Below is an example to save the cropped image to file system.

<p:imageCropper value="#{cropper.croppedImage}" image="/campnou.jpg" />

<p:commandButton value="Crop" actionListener="#{myBean.crop}" />
