[Zope] ZClasses: Object Manager's containing renameable Object Manager's

I've created a ZClass that inherits from Object Manager. I want it to hold another type of ZClass/Object Manager. The problem is I need to manage_renameObject() the Object Managers that are inside Object managers and when I do I get "The object foo does not support this operation." The sub-object managers were created in side the method's view of the parent-object managers. So, I tried inheriting from Folder instead of Object Manager and I can't get the option to add the sub-folder objects to show up on the menu. Any help is greatly appreciated. ^Roman
