Sorry for asking again: What may be problem if the very same <tr:tree> component (same Model) does work perfectly inside the contents of a <tr:panelPage> but does not expand if it is pushed inside the "navigation3" facet of the panelPage?
In both cases it is inserted by Facelets, in the working version from the page, in the non-working version from the template the page uses. The icons on the root nodes indicate correctly which one has children and which one does not (I subclassed ChildPropertyModel to get this), but on click nothing happens inside navigation3. Thanks in advance! sonja
