[Zope] Base classes for a folderish portal type (CMF)

[katrin]

Hi everyone,

I'm trying to create a ZClass as a base for a folderish portal type. Now
it seems I have a problem with the Base classes for my ZClass. When I try
to add my portal type as a user in the portal, I get the following error
message:

         Zope Error

         Zope has encountered an error while publishing this resource.

         Error Type: AttributeError
         Error Value: creation_date

The problem seems to be the DublinCore but one of my ZClasses base class
is the DefaultDublinCoreImpl.

Does anyone know which classes are necessary?=20

Thanks,
