[Zope] Access method of a secondary base class

[Fabio Rolando]

Hi

I created a ZClass with a few base classes, namely:

ZObject, CatalogPathAwareBase, ZDTMLDocument, ZObjectManager  (in this order)

Now, when I access the manage_main method of objects of this class I'm 
shown the usual interface for DTMLDocuments.

How can I access the Contents view that my objects inherit from ZObjectManager.

Thank you
