[Zope-dev] __ac_permissions__ question

If I define the following in an Article class (which subclasses Posting): __ac_permissions__ = Posting.__ac_permissions__ + ( ('View', ['prev_item','next_item','showSummary','desc_items'], ('Anonymous', 'Manager')), ) and Posting.__ac_permissions__ also defines a 'View' permission, which methods are covered? (the ones from Posting, the ones from Article or (hopefully) the union of the two sets of methods) cheers, Chris PS: If it's nto the union, how can I achieve this effect?
