Tapestry's exception report page is quite rich and informative. We've gone to great difficulty to track what Tapestry is up to at all times during a request, and we also show you full details for the most deeply nested exception. It's always important to take a deep breath and scan down the full exception report page; often you can save yourself a lot of time and stress by just reading what Tapestry has to tell you. Even I sometimes stumble on this, during the stress of a training, but more often than not, the answer I need is right in front of my eyes. -- Howard M.
