Two answers to this: 1) whatever you do to validate, do it in validators. That's the way we currently go, and I don't see a reason not to do it. It's the clean road. 2) if you insist on doing it your way, I can only guess, but after a peek into tg.controllers it appears as raising a formencode.Invalid-exception from your controller *might* actually do what you want. Did you try that? If you are successful with the second approach, it would be good if you could come back here to tell us about that, so we know for future reference.
