[Zope3-Users] Error when calling addform

[David Johnson]

Many people have offered approaches.  I find the simplest and  
cleanest approach for declaring interfaces is as follows:

class IContactList(IContainer):
       contains('.IContact')

class IContact(Interface):
       ...schema fields...

class IContactContained(IContained):
       containers(IContactList)

Basically, the schema used in your addform CANNOT include IContained.
