[Zope-dev] Attribute Error: __bases__

[Jonas Juselius]

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?

Best regards,
                jonas
