[Zope3-Users] Re: Conflicting configuration actions for protectName __setitem__

[Rob Campbell]

Ok, that's what I thought.  How can I fix the problem?  I think I can 
create an IFosterSourceContainer interface and have the constraint 
there.  Then I would have to implement that interface for FosterRecord. 
  Would that work?  Also, is there any other/better way to do it?
