[Zope3-Users] Containers Contains

[David Johnson]

When setting up container/contained relationships, what is the proper  
approach? Is it the approach outlined in Stephan's book with  
IContainer, __setitem__, and preconditions?  Or is it "contains" and  
"containers"?

I have been having some problems and would be curious the definitive  
approach.  The former is more complicated and so I find make lots of  
coding errors.  The latter is simple but I find it causes strange  
IInputWidget errors.
