Hi
I tried the following example:
<h:form id="mainForm">
<test:ajaxPanel2
onRowEditListener="#{ajaxListenerBean.ajaxRender}"
value="#{ajaxListenerBean.value}"/>
</h:form>
ajaxPanel2.xhtml
<cc:interface>
<cc:attribute name="onRowEditListener" required="false"
method-signature="void
listener(javax.faces.event.AjaxBehaviorEvent)"/>
<cc:attribute name="value"/>
</cc:interface>
<cc:implementation>
<test:ajaxContent onRowEditListener="#{cc.attrs.onRowEditListener}">
<h:outputText value="#{cc.attrs.value}" />
</test:ajaxContent>
</cc:implementation>
ajaxContent.xhtml
<cc:interface>
<cc:attribute name="onRowEditListener" required="false"
method-signature="void
listener(javax.faces.event.AjaxBehaviorEvent)"/>
</cc:interface>
<cc:implementation>
<h:commandButton value="Press me">
<f:ajax render="content" listener="#{cc.attrs.onRowEditListener}" />
</h:commandButton>
<h:panelGroup id="content" layout="block">
<cc:insertChildren/>
</h:panelGroup>
</cc:implementation>
@ManagedBean
@RequestScoped
public class AjaxListenerBean
{
private String value;
/*... getter and setter ..*/
public void ajaxRender(AjaxBehaviorEvent evt)
{
value = Double.toString(Math.random());
System.out.println("value ="+value);
}
}
Works without problem. I'm using jetty maven plugin 8.1.3.v20120416 ,
which uses glassfish EL.
There is no evidence so far that there is a bug in MyFaces. That part
has been tested intensively. I think it is a bug in tomcat EL
implementation or maybe something related to openwebbeans
EL10ValueExpression.
