[TurboGears] Re: Identity crisis

[Jeff Watkins]

Actually, I found the problem and it WAS in my code, only Kid made it 200 times more difficult to track down the problem. See my most recent message in the "SQLObject transaction problems" thread. I agree that debugging TurboGears applications is nightmarish at the moment. I can only hope that's going to improve. At least when I was doing JSPs, I had some prayer of knowing what line the error appeared on.
