Hm... are you sure you aren't env.pop'ing that PageId somewhere else? It really
ought to still be available in environment in AfterRender. Thiago is correct
that you don't /have/ to pop it since the service is per-thread, but it's
disturbing to me that it's not there in AfterRender... unless one of your
SubPage classes is "pop" ing it instead of "peek" ing it?
