Hi Chris, Thanks for your response. I actually don't invalidate the current session there. That's what is so frustrating -- the code snippet I provided is at the very top of the method, and there's no more reference to the session or request until using setAttribute.
I don't mind providing the code -- it's at http://java.pastebin.ca/1283742. Actually, looking at it in the pastebin -- could it be that I'm setting an attribute FOR the error about a missing session? Hmm.... did I just solve my own problem? Martin Christopher Schultz wrote: > Martin, > > Martin B.
