hi, i have a a4j:poll tag on my page which has a small time interval value. (smaller than session timeout). It runs perfectly in a tab. But if i logout from another tab. (close my session). In the first tab i got immediately a very BORING alert dialog : View state could't be restated. reload page? and errors | 16:32:08,058 ERROR [ExceptionFilter] exception root cause | java.lang.IllegalArgumentException: Stack must not be null | at org.jboss.seam.core.ConversationEntry.<init>(ConversationEntry.java:39) | at org.jboss.seam.core.ConversationEntries.createConversationEntry(ConversationEntries.java:53) | at org.jboss.seam.core.Manager.createConversationEntry(Manager.java:510) | at org.jboss.seam.core.Manager.beforeRedirect(Manager.java:651) | at org.jboss.seam.faces.FacesManager.beforeRedirect(FacesManager.java:63) | at org.jboss.seam.faces.FacesManager.appendConversationIdFromRedirectFilter(FacesManager.java:222) | at org.jboss.seam.web.RedirectFilter$1.sendRedirect(RedirectFilter.java:65) | at com.sun.faces.context.ExternalContextImpl.redirect(ExternalContextImpl.java:419) | at org.ajax4jsf.framework.ajax.AjaxViewHandler.restoreView(AjaxViewHandler.java:180) | at org.jboss.seam.jsf.SeamViewHandler.restoreView(SeamViewHandler.java:93) | at com.sun.facelets.FaceletViewHandler.restoreView(FaceletViewHandler.java:316) | at com.sun.facelets.FaceletViewHandler.restoreView(FaceletViewHandler.java:316) | but when i use SEAM 1.3.0Alpha , page was redirected to login page smoothly without such BORING alert and exception..... how can i suppress this stupid dialog?
