[Zope3-Users] Custom Content Container

[Tom Gross]

Hi David,

which fields does your IOwner-interface consist of? You get this error 
if you call an auto generated form from a List-field, without
having value_type specified, but there are other scenarios, so this 
information would be helpful.

Cheers
-Tom
