Is there a graceful way to detect a session expiration. Currently I get a nasty error message about a required @In when the session expires.
The best I can figure is to set all of my @In(required=true) to false and check manually for null. Obviously this would beg the question why we would use true at all.
Or am I to much of a nube and have missed something in the documentation.
Are you referring to conversation timeouts or session timeouts?
Session timeouts can be handled gracefully a number of ways (filters, @LoggedIn annotations etc).
Conversation timeouts are a little more subtle - perhaps someone can shed some light.
