This is the second time I have been answered that it is possible without indicating the way to do it. Please do ... I have done my best to read PortalNodeEventListener, WindowNavigationEvent and could not find any way of doing this there. Same issue for changing region for a portlet, where, when? By the way, I posted an example of a real concept of layout - layout being able to embed layout - Ajax dev kit have this now well defined, not only YUI. This really is layout and is needed.
