Sounds like tapestry-security is doing the right thing, no? How I would solve the problem, is that either I wouldn't let the session to expire or warn the user that the session is about to expire, or a combination of both. If you added conversational scope, it'd be relatively easy to do (see http://tynamo.org/tapestry-conversations+guide for more info).
