I'm running RF 3.3.3.Final with MyFaces 2.0.4. I find that my views are expiring. The reason is that every time a4j:poll does a poll, it adds another view to the session's seralized_view. (session attribute org.apache.myfaces.application.jsp.JspStateManagerImpl.SERIALIZED_VIEW). Since the default is to only save 20, eventually it uses all 20 and another page that attempts to do a post gets a view expired error. Is it intended that every postback serializes its own copy of the view?
