[Zope3-Users] Conflicting configuration actions for protectName __setitem__

[Rob Campbell]

Hi Darryl,

That is how I had the IFosterRecord interface before, and I got a lot 
more errors than just __setitem__.  I am only getting the __setitem__ 
error now, after changing it to something like:

class IFosterRecord(Interface):

   contains('.IFosterSource')

   title = TextLine(...)

and the implementation is:

class FosterRecord(BTreeContainer):

   implements(IFosterRecord)

   title = FieldProperty(IFosterRecord['title'])

I think the problem is coming from contains().  Do I need to create 
another interface just for the contains()?  Maybe something like 
IFosterSourceContainer.  Or is there another way to fix this error? 
Thank you for the reply.
