I am trying to bind a composite component to an ajax listener but the bind variable resolves to null. If I use the bind variable as part of the body, eg. #{bind} it does resolve properly. I assume it is a bug, but would like a second opinion before I report it. Thanks

This is a bug. See here for details.

I'm trying to create a simple composite component based on JSF h:panelGroup:
filter.xhtml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:composite="http://java.sun.com/jsf/composite"
xmlns:p="http://primefaces.org/ui">
<composite:interface>
</composite:interface>
<composite:implementation>
<span>Расширенный фильтр</span>
<h:panelGroup id="#{cc.clientId}" class="filter"
style="background:white">
<composite:insertChildren></composite:insertChildren>
</h:panelGroup>
</composite:implementation>
and place a component that has to be partially submitted inside it.
<h:form id="issueFilterForm" prependId="false">
<c3:filter>
<h:panelGrid columns="2">
<h:outputText value="Продукт:" />
<p:selectOneMenu value="#{issueFilterBean.selectedProd}"
filter="true" filterMatchMode="contains">
<f:selectItem itemLabel="Выберите продукт" itemValue="-1" />
<f:selectItems value="#{issueFilterBean.products}" var="proj"
itemLabel="#{proj.name}" itemValue="#{proj.id}" />
<p:ajax event="change" process="#this" update="#form"
partialSubmit="true" />
</p:selectOneMenu>
</h:panelGrid>
</c3:filter>
</h:form>
The p:ajax call is fired, but no partial submission takes place. If i remove enclosing c3:filter, the submission works well.
How can I make this not skipping partial submission?
Is there any way to trigger an event in my composite component with clientBehavior and jQuery?
If not possible, what is the proper way to create custom events in composites?
Example:
ajaxTest.xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:cc="http://xmlns.jcp.org/jsf/composite"
xmlns:p="http://primefaces.org/ui">
<cc:interface>
<cc:clientBehavior name="myEvent" targets="myLabel" event="myEvent"/>
</cc:interface>
<cc:implementation>
<div id="#{cc.clientId}">
<p:outputLabel id="myLabel" value="Test label" />
<p:commandLink value="trigger event"
onstart="$(PrimeFaces.escapeClientId('#{cc.clientId}:myLabel')).trigger('myEvent');"/>
</div>
</cc:implementation>
</html>
testPage.xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:demo="http://xmlns.jcp.org/jsf/composite/component">
<h:body>
<h:form id="form-1">
<demo:ajaxTest>
<p:ajax event="myEvent" oncomplete="alert('Ajax called');" />
</demo:ajaxTest>
</h:form>
</h:body>
</html>
The <cc:clientBehavior event> must declare a valid event name as supported by the target component in question. In this context, it must thus be exactly the same event name as you would use when nesting <p:ajax> directly inside <p:commandLink>. You perhaps want action or click.
<cc:clientBehavior ... event="action" />

What values can I pass to the event attribute of the f:ajax tag?
I have spring integrated with JSF and I am facing a strange behavior:
I hit the command button the action method in the managed bean is hit successfully (I removed it in the below example).
The Ajax update works perfect and the form is updated.
I hit another button the action method now in the managed bean isn't hit.
The panel is restored to the initial view and it freezes on this view.
I can't get the form updated except if I refresh the page and these steps are repeated.

Update:
I created a very simple single page and I noticed that when I remove the <h:head></h:head> tags the ajax works like a charm BUT without the fancy primefaces UI, and when I add the tags the ajax stop (this is normal cause <h:head></h:head> tags fetch all the needed JSs and CSSs), What Can I Do?

My Environment
Primefaces:3.5
JSF-Mojarra:2.2
Spring:3.2.3.RELEASE
In case anyone faces the same issue. I noticed that the Primefaces showcase is using JSF-Mojarra-2.1.22. I downgraded my JSF-Mojarra version from 2.2 to 2.1.22 and it worked like a charm.
If I am not wrong, I guess it should be reported to primefaces (if it isn't a current issue).
this is my 1st question here :)
My code is as follows:
<?xml version="1.0"?>
<f:view xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
>
<h:head />
<h:body>
<h:form id="filterForm">
<h:outputStylesheet library="css" name="main.css" />
<div id="filterPane">
<h:panelGroup rendered="#{not empty filters.categories}">
<div class="filter">
<div class="filterCategories" style="width: 100%;">
<h4>Kategorien</h4>
<p />
<h:selectManyCheckbox layout="pageDirection"
value="#{filters.selectedCategories}"
valueChangeListener="#{filters.categoryValueChanged}">
<f:selectItems value="#{filters.categories}" var="category"
itemLabel="#{category.displayName} (#{category.count})"
itemValue="#{category.name}" />
<f:ajax render="#form" />
</h:selectManyCheckbox>
</div>
</div>
</h:panelGroup>
</div>
</h:form>
</h:body>
</f:view>
I get the same error as some others before me here #stackoverflow - but none of the suggested solutions worked for me.:
<f:ajax> contains an unknown id 'A5539:filterForm:j_idt9' - cannot locate it in the context of the component j_idt9
Before my switch from <p:selectManyCheckbox to <h:selectManyCheckbox the code was working fine.
We need to change to <h:selectedManyCheckbox, because the PrimeFaces variant is not selectable for a non-JavaScript user. I need the form <h:form id="filterForm"> to be re-rendered as a consequence of my AJaX request via the <f:ajax> element.
Beside the initial <f:ajax render="#form" /> I unsuccessfully tried to reference the <h:form id="filterForm"> element with the following variants:
<f:ajax render=":filterForm" />
<f:ajax render=":#{component.parent.parent}" />
I also tried some more stupid ones.
Any hint, anybody!? :)
We have a list to be displayed under a panel of the screen where all the code in which the fields are repeatable are kept under a different Facelet file. While I am trying to render an image based on the listener's action for an ajax event I am getting some problem to update the image with ID as JSF is generating an ID with the index in the middle due to the use of <ui:repeat> like so repeatForm:repeat:2:redimage.
This is the main page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:c="http://java.sun.com/jsp/jstl/core">
<h:head>
<title>Repeat Test Demo</title>
</h:head>
<h:body>
<h:form id="repeatForm">
<ui:repeat id ="repeat" value="#{listBean.xyzList}" var="repeatListVar">
<p:panel id="genLiabPanelRender">
<ui:include src="MyScreen.xhtml" />
</p:panel>
</ui:repeat>
</h:form>
</h:body>
</html>
This Facelet is repeatable based on the list size within the panel.
MyScreen.xhtml this is the include Facelet file:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.prime.com.tr/ui">
<h:body class="body">
<h:panelGrid columns="4" border="0" width="90%">
<h:panelGroup style="display:block;text-align:left;width: 320px">
<h:selectBooleanCheckbox value="#{repeatListVar.primaryPolicyInd}" />
<h:outputText value="#{label.primaryCov}" />
</h:panelGroup>
<h:panelGroup style="display:block;text-align:left;width: 240px">
<h:selectBooleanCheckbox value="#{repeatListVar.abcInd1}" />
<h:outputText value="#{label.commGenLiab}" />
</h:panelGroup>
<h:panelGroup style="display:block;text-align:left;width: 180px">
<h:outputText value=" #{label.eachOccur}" style="text-align:left" />
</h:panelGroup>
<h:panelGroup style="display:block;text-align:left;width: 130px">
<p:inputMask mask="#{label.limitAmtMask}" id="genLiabEachOccAmt"
value="#{repeatListVar.a25GLEOAmt}" required="true"
style="width: 90px">
<f:ajax event="blur" render="redimage" listener="#{repeatListVar.testA25GLEOAmt}"/>
</p:inputMask>
<h:graphicImage id="redimage" url="/images/icons/redIcon.png" rendered="#{repeatListVar.testA25GLEOAmtInd}" />
</h:panelGroup>
This ends up generating IDs for the <h:outputText> that look like: repeatForm:repeat:2:redimage. But because we're using the <f:ajax> tag, we only need to specify "redimage". The tag takes care of the work of finding out what the real ID is.
We are calling a method in the listener and set the value of boolean indicator to either true or false which is false by default. The indicator is used to render the image.
But when we are using this <f:ajax> to render the image based on the indicator value, I am getting the error
malformedXML: During update repeatForm:repeat:2:redimage not found
How is this caused and how can I solve this?
This should work. I see only 2 possible causes:
Your bean is request scoped and does not preserve the <ui:repeat> value. Fix the bean constructor's job and/or put the bean in the view scope.
Your HTML output is syntactically invalid and is therefore confusing the JavaScript code who is responsible for updating the HTML DOM tree. You should not use <html> and <h:body> in the include file. It would be duplicated in the HTML output. You should only use it in the master page. The include page should look like this:
<ui:composition
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:panelGrid columns="4" border="0" width="90%">
...
</h:panelGrid>
</ui:composition>
Do not duplicate <html>, <h:head> and/or <h:body> in there.
