Since it's not a Tapestry-related request, control has passed out of
the TapestryFilter and on to other servlets within the web
application. Tapestry has already cleaned up the RequestGlobals
object, a per-thread service that stores the HttpServletRequest and
(Tapestry) Request objects.
You want to make sure to invoke the Registry.cleanupThread() method at
the end of your request.
I've been planning to add a simpler alternative to
SessionStateObjects, an annotation that simply says "store this value
in the session with this explicit key", to make coordinating a T5 app
with a legacy app simpler.
