[Zope] 'manage_pasteObjects()' problem

When I execute the following python code (from within a method of an instantiated object): myClipboard = self.aq_parent.manage_cutObjects(id) destination_folder = getattr(my_root_folder,'dest') destination_folder.manage_pasteObjects(myClipboard) I get the error: 'The object <my object id> does not support this operation.' And I don't get it. I thought that by making my object inherit from 'OFS.SimpleItem.Item', I get cut&paste support. Can someone explain? What's the solution to make 'paste' functionality work? Or again, are there alternative tricks for moving objects around, besides 'manage_pasteObjects()'? Regards, Vio
