How can I invalidate session other than the current one? I create an application scoped session map but when I try and call HttpSession.invalidate I get an IllegalStateException? What is the best alternative? setting a session attribute "org.jboss.seam.sessionInvalid" will causing subsequent JSF requests from that session to invalidate (Remoting requests I don't think will invalidate), but that can still leave a chunk of memory wasted.
