Gracefully Handling Timeouts
Hello,
My application header has a welcome message like this (where "session" is a session-scoped component).
Welcome, #{session.loggedInUser}
Usually works fine, but my problem is if the session times out I either see (depending on the phases of the moon) "Welcome," (no name at all) or an exception like below.
What can I do to gracefully handle timeouts of sessions (or conversations for that matter)? Do I have control of what happens (i.e. callbacks) when timeouts occur? I'd prefer session timeouts to log out my Identity and conversation callbacks to redirect to a "conversation-neutral" page I define.
Any ideas greatly appreciated.
Greg
