[Zope] Re: Question about dot in method name

[bard stéphane]

__getitem__ raise an exception :
*Error Type: AttributeError*
*Error Value: 'super' object has no attribute '__getitem__'

my class derive from
    (ObjectManager, BTreeFolder2, PropertyManager):
I test :
**    (ObjectManager, Folder PropertyManager):*
**and got the same exception

the method of Sascha is working (This is a satisfaction). but i'm
very interesting to understand the method proposed by Martijn.
