Hi,

The c:if testcase in 
org.apache.myfaces.view.facelets.tag.jstl.core.JstlCoreTestCase.testIf() 
contains code to trigger a component tree rebuild for jstl tags:

        // make sure the form is there
        e.setManagement(true);
        vdl.buildView(facesContext, root,"if.xml");
        UIComponent c = root.findComponent("form");
        Assert.assertNotNull("form is null", c);
// now make sure it isn't
        e.setManagement(false);
facesContext.setViewRoot(facesContext.getApplication().getViewHandler()
                .createView(facesContext, "/test"));
        root = facesContext.getViewRoot();
        vdl.buildView(facesContext, root,"if.xml");
        c = root.findComponent("form");
        Assert.assertNull("form is not null", c);

I'm trying to use this technique in an AJAX action (because I've got a 
recursive page structure which requires a c:forEach and an AJAX request to 
toggle parts of it).

Effect: MyFaces is not sending an AJAX response at all any more and comes back 
with a malformedXML error. Is this a bug or does the above code need to be 
changed for AJAX requests?

Best regards,
Ganesh
