Can you guys give me some tips to track down the cause of a SessionRestoreError? As I understand it, it''s generally caused by a controller accessing something from the session without having the right classes defined. The classic case is calling @session[''user''] without having loaded the User class. So far as I can tell, my controllers are correct: they have the right ''model'' declarations. Can anyone suggest any tricks to use to locate the cause of the problem? Thanks, Gavin
