Hello all, I have encountered a strange problem: the tuple 'class.__bases__' has disappeared. It should be a Python defined variable, but it's gone... The problem manifested it self by trying to call 'manage_access()' of a Product I'm working on, which resulted in: Error Type: AttributeError Error Value: __bases__ in gather_permissions() in RoleManager. My class inherits (ObjectManager, PropertyManager, RoleManager, SimpleItem), which is basicly what a Folder inherits. A funny thing is that if I inherit Folder instead, the problem disappears. I also tried a method 'returnBases(self): return self.__bases__' of my class, and it does not work (results in the same error). Any clues?
