Everything there looks kosher at first glance to me. SessionVars should stay
in the session no matter what. One thing I can think of is if somehow you're
losing the session. Is the session ID being stored in a cookie, or as part
of the URI? If it's part of the URI you may be dropping it somewhere else in
your code if you process the URI at all. That's just a guess. Also, I would
probably write the isAuthenticated method as:
def isAuthenticated_? : CurrentUserId.map(true) openOr false
