Please note that this is a CMF 2.1 specific issue.

CMF trunk (2.2) has a separate IOpaqueItemManager interface, 
dispatchToOpaqueItems is no longer registered for IDynamicType:

http://svn.zope.org/?view=rev&rev=85187

CHANGES.txt says:
"In the long run ICatalogAware, IWorkflowAware and IOpaqueItemManager 
will become deprecated. Don't expect that CMF content always implements 
them."


Cheers,
