ViewExpiredException, Page could not be restored
I've tried to follow different posts on how to handle the ViewExpiredException in Mojarra 2.1.0 (with RichFaces 4) on GlassFish 3.1. But what I define in web.xml doesn't seams to have any effect. I use form base security and the user has to logon to access the content. I just want Glassfish (catalina) to redirect the user to a simple JSF page when the session times-out, with a link back to the login page.
I always get the the following error message;
javax.faces.application.ViewExpiredException: viewId:/app_user/activity/List.xhtml - View /app_user/activity/List.xhtml could not be restored.
at com.sun.faces.lifecycle.RestoreViewPhase.execute(RestoreViewPhase.java:202)
at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101)
at com.sun.faces.lifecycle.RestoreViewPhase.doPhase(RestoreViewPhase.java:113)
Who can I redirect the user when the user session has timed-out and trap the exception in the server log ?
Greetings, Chris.

Answer
Your approach should work perfectly fine for synchronous POST requests. However, you're using asynchronous (ajax) POST requests. Exceptions on ajax requests needs to be handled by either the jsf.ajax.addOnError init function in JavaScript or a custom ExceptionHandler.
