I don't believe it!!!!:

$('id_of_the_parent_div').getElementsByClassName('message_#{msg.id}')[0]

it is resolved to null on what JSF lifecycle phase? 2nd or 6th?

Sergey, I used a phase listener. The id isn't null in any phase. And this code works:

<a4j:include viewId="/abc.xhtml" rendered="#{barBean.viewId=='abc'}"/> <a4j:include viewId="/def.xhtml" rendered="#{barBean.viewId=='def'}"/>

It appears that only the viewId cannot be dynamic. Can you please confirm?

Thanks.

On my project, I got a <a4j:include> with a dynamic viewId, I change its value and than rerender it with a command link and it works...

Ziphyre, can you please post the code before and after the a4j:include? And, are you using Facelets?

Sorry for the late reply,

Here is a sample working code.

Ps: I use seam but in the same result can be done with faces-config managed beans...
grimholtz: yes I'm using facelets 1.1.14

test.xhtml:

 <a4j:commandLink value="Toggle View" action="#{testBean.toggleView}"
 reRender="testForm" />
 </h:form>

 <h:form id="testForm">
 <a4j:include viewId="#{testBean.viewId}" />
 </h:form>
</body>

</html>

test1.xhtml

TestBean.java:

import org.jboss.seam.annotations.Scope;


@Name("testBean")
@Scope(ScopeType.SESSION)
public class TestBean {
 private String viewId;

 public TestBean() {
 viewId = "/test1.xhtml";
 }

 public String getViewId() {
 return viewId;
 }

 public void setViewId(String viewId) {
 this.viewId = viewId;
 }

 public void toggleView() {
 if ( getViewId().equals("test1.xhtml") ) {
 setViewId("test2.xhtml");
 }
 else {
 setViewId("test1.xhtml");
 }
 }
}

I never was able to get a4j:include to use an EL expression for viewId. Instead, I read these articles:

http://www.ilikespam.com/blog/c:foreach-vs-ui:repeat-in-facelets [it's helpful to read the comments at the end, too]
http://wiki.java.net/bin/view/Projects/FaceletsFAQ#Why_doesn_t_my_c_if_ui_repeat_ui
http://andrewfacelets.blogspot.com/2008/03/build-time-vs-render-time.html

and used ui:include inside c:forEach (note I'm using facelets).

Hi guys,

Has anyone found a solution for this ?

I am using RF 4, and I am trying to set the id of tree node from backing bean, hopeing to set a default selected node.
