The Plan
● Ajax features in JSF 2
● The new RichFaces 4

Exadel

JSF 2
● JSF 2 is a major upgrade over JSF 1.x
● Many features, ideas taken from
projects such as Seam and RichFaces,
and others

Exadel

JSF 2 new features
● Facelets ● New scopes
● Composite ◦ Flash, View,
components custom
● Navigation ● Configuration

● GET support ◦ Annotations
● BeanValidation
◦ Page parameters
support
◦ h:link, h:button
● Ajax
● Resource loading

Exadel

JSF 2 <f:ajax>
● Basic Ajax functionality
● Greatyinspired by RichFaces 3
<a4j:support> tag
● Ajax in JSF in 3 easy steps:
◦ How to send an Ajax request
◦ Partial view processing
◦ Partial view rendering

Exadel

2. What to execute on the
server:
● @all 1. <f:ajax> and event takes
● @this (default) care of firing the Ajax
● @form request
● @none

● Id's

● EL

<h:commandButton>
<f:ajax event="click"
execute="@form"
render="@form id1 id2"/>
<h:commandButton>
3. Partial view rendering:
● @all

● @this

● @form

● @none (default)

● Id's

● EL

Exadel

Using <f:ajax>
<h:commandButton value="Submit" action="#{bean.action}" >
<f:ajax event="focus" execute="@form" render="output"/>
</h:commandButton>
<h:panelGrid id="output">
... Attaching to button,
specifying event
</h:panelGrid>

<h:commandButton value="Submit" action="#{bean.action}" >
<f:ajax execute="@form" render="output output2"/>
</h:commandButton>
...
</h:panelGrid>
<h:panelGrid id="output2">
... No event specified,
</h:panelGrid> using default event

Exadel

Using <f:ajax>
Default event is onchange

<h:inputText value="#{bean.text}" >
<f:ajax event="keyup" render="text"/>
</h:inputText>
<h:outputText id="text" value="#{bean.text}" />

No event specified so using default

<h:selectOneListbox id="list" value="#{bean.choice}" >
<f:selectItems value="#{cean.choiceList}" />
<f:ajax render="info" listener="#{bean.change}"/>
</h:selectOneListbox>

<h:panelGrid id="info">
...
</h:panelGrid>

Exadel

<f:ajax>
<h:panelGrid> No default event, no Ajax added
<h:selectBooleanCheckbox> onchange
<h:inputText> onchange
<h:commandButton> onclick
</h:panelGrid>
</f:ajax>

<f:ajax event="click">
<h:panelGrid> onclick
<h:selectBooleanCheckbox> onclick
<h:inputText> onclick
<h:commandButton> onclick and onfocus
<f:ajax event="focus"/>
</h:commanButton>
</h:panelGrid>
</f:ajax>

<f:ajax event="valueChange">
<h:panelGrid> No Ajax added
<h:selectBooleanCheckbox> onchange
<h:inputText> onchange
<h:commandButton> onfocus
<f:ajax event="focus"/>
</h:commanButton>
</h:panelGrid>
</f:ajax>

Exadel

That's good, but a rich
component framework is still
need to build real-world
Ajax applications.

Exadel

RichFaces 4 – rich JSF
framework
● JSF 2 based
● Ajax components

◦ a4j:* tag library (core)
◦ rich:* tag library (UI)
● Skins and themes
● CDK – Component Development Kit

Exadel

RichFaces versions

Version JSF 1.1 JSF 1.2 JSF 2

RichFaces 3.1.x •
RichFaces 3.3.3* • •
RichFaces 4 •
* Note: RichFaces 3.3.3 has basic JSF 2 support

Exadel

What about deployment?

Any server

All browsers (even IE 6)

Exadel

RichFaces history
2005: started by Alexander Smirnov
2005-2007: Developed by Exadel
Ajax4jsf – open source, free
RichFaces - commercial
2007: JBoss takes over
Exadel team continues to develop
the framework

Exadel

Just tell me when RichFaces 4
is going to be released?

Exadel

RichFaces 4

JavaScript in RichFaces is
now entirely based on the
popular jQuery library.

Exadel

RichFaces 4
● All components are reviewed for
consistency, usability
● Redesigned following semantic
HTML principles
● Server-side
and client-side
performance optimization
● Strict code clean-up and review

Exadel

RichFaces 4
● Newand easy to use CDK
(Component Development Kit)
● Quickly build your own custom rich
components

Exadel

Google App Engine
● DeployRichFaces application in
Google App Engine (GAE)
● Special maven-based plug-in
available

Exadel

RichFaces <a4j:ajax>
● 100% based on standard <f:ajax>
● Just replacef: with a4j: and get
exactly the same functionality
● But, you get extra features...

Exadel

<a4j:ajax> attributes
Attribute Description

onbegin JavaScript to execute before Ajax request
JavaScript to execute after response
onbeforedomupdate
comes back but before DOM update
oncomplete JavaScript to execute after DOM update
Skips Update Model and Invoke
bypassUpdates Application phases, useful for form
validation
Skips all a4j:outputPanel
limitRender ajaxRender=”true” areas. Only renders
what is set in current render
status Status to display during Ajax request

Sets focus on component after Ajax
focus
request

Exadel

RichFaces 4
That's not all, there are more RichFaces
goodies...

Exadel

RichFaces 4 core action –
fire an Ajax request
● a4j:ajax
● a4j:commandButton
● a4j:commandLink
● a4j:jsFunction
● a4j:poll
● a4j:push

Exadel

<a4j:commandButton> –
Ajax button
/* standard button with f:ajax */
<h:commandButton value="Save" action="#{bean.action}">
<f:ajax execute="@form"
render="output"/>
</h:commandButton>

/* RichFaces button */
<a4j:commandButton value="Save"
execute="@form"
render="output"
action="#{bean.action}" />

Exadel

<a4j:jsFunction> – fire Ajax
request from any JavaScript
function
<table>
...
<td onmouseover="update('yellow')"/>
...
</table>
<a4j:jsFunction name="update"
action="#{bean.change}"
reRender="panel">
<a4j:param value="param1" assignTo="#{bean.color}"/>
</a4j:jsFunction>

Exadel

<a4j:poll> – periodically
send an Ajax request

<a4j:poll interval="1000"
action="#{bean.count}"
render="output"
enabled="#{bean.pollEnabled}" />

...
</h:panelGrid>

Exadel

RichFace 4 core – output,
panels
● a4j:outputPanel
● a4j:status
● a4j:region
● a4j:queue
● a4j:repeat
● a4j:log

Exadel

<a4j:outputPanel> – auto
rendered panel

<h:selectOneMenu value="#{bean.fruit}">
<a4j:ajax listener="#{bean.change}"/>
</<h:selectOneMenu>
<a4j:outputPanel ajaxRendered="true">
<h:panelGrid>
...
</h:panelGrid> Rendered on every
<h:panelGrid> Ajax request
...
</h:panelGrid>
</a4j:outputPanel>

Exadel

<a4j:status> – Ajax request
status

<a4j:status name="ajaxSpecial">
<f:facet name="start">
<h:graphicImage value="ajaxStatus.jpg"/>
</f:facet>
</a4j:status>

<h:form>
<inputText />
<inputText />
<a4j:commandButton status="ajaxSpecial"/>
</h:form>

Exadel

<a4j:region> – declaratively
define execute region
<h:form> Execute options:
@all●

<a4j:region> @this (default)
●

<h:inputText /> @form
●

<h:inputText /> @none
●

Id's●

<a4j:commandButton execute="@region"/> EL ●

<a4j:region> @region
●

</h:form>

<h:form>
<a4j:region>
<h:inputText />
<h:inputText />
<a4j:commandButton />
<a4j:region>
</h:form>

Exadel

<a4j:log> – Ajax request
information
● Levels:

◦ debug, info, warn, error

Exadel

JavaScript interactions
<h:commandLink value="Link"
<f:ajax onevent="ajaxFunction();">
</h:commandLink>
Called three times:
1) begin
2) success
3) complete

<a4j:commandLink value="Link"
onbegin="alert('Link clicked')"
onbeforedomupdate="alert('Response received')"
oncomplete="alert('DOM updated')">
</a4j:commandLink>

Events are separated

Exadel

Advanced rendering options

<a4j:commandButton render="output"/>
<a4j:commandButton render="output" limitRender="true"/>

Turns off all auto rendered panels,
...
only renders what is set in current
</h:panelGrid> render

<a4j:outputPanel ajaxRendered="true">
...
</a4j:outputPanel>

Exadel

Skipping
phases
when
validating
1.Restore View
2.Apply Request Values
3.Process Validation
4.Update Model
5.Invoke Application
6.Render Response

<h:inputText id="name" value="#{bean.name}"/>
<a4j:ajax event="blur" bypassUpdates="true"/>
</h:inputText>
<rich:message for="name"/>

Exadel

JSF 2 queue
● JSF2 has very basic queue
functionality
● Events are queued and fired one at a
time
● Only one request is processed on the
server at a time

Exadel

RichFaces queue upgrades
● Delay firing of a request
● Combine requests from one or more controls
● Cancel DOM updates if the same request was
fired
● Define queue as:
◦ Global (all views have queue)
◦ View-based
◦ Form-based
◦ Named (used by particular components only)

Exadel

RichFaces <a4j:queue>
<a4j:queue requestDelay="2000"/>
... Delay request
by 2 seconds
<a4j:commandButton value="Button1"/>
<a4j:commandButton value="Button2"/>

... Overwrite default
<a4j:commandButton> delay request
by 1 second
<a4j:attachQueue requestDelay="1000"/>
</a4j:commmandButton>
<a4j:commandButton />

Exadel

a4j:queue – “combining”
events

...
<a4j:commandButton>
<a4j:attachQueue requestGroupingId="mainGroup"/>
<a4j:commandButton>
<a4j:attachQueue requestGroupingId="mainGroup"/>

Exadel

a4j:queue – ignoring “stale”
responses
<a4j:queue requestDelay="2000
ingoreDupResponses="true"/>

<h:inputText value="#{bean.state}">
<a4j:ajax event="keyup"
listener="#{bean.load}"
render="states"/>
</h:inputText>

<rich:dataTable id="states">
<rich:column/>
</rich:dataTable>

Exadel

RichFaces UI components
