Hi there, I've created a custom folder which has some addable products defined inside it. When I add such a product and try to copy and paste it, I get this traceback: The object test does not support this operation Traceback (innermost last): File /home/zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /home/zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /home/zope/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook File /home/zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /home/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_pasteObjects) File /home/zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_pasteObjects) File /home/zope/lib/python/OFS/CopySupport.py, line 199, in manage_pasteObjects File /home/zope/lib/python/OFS/CopySupport.py, line 374, in _verifyObjectPaste Copy Error: (see above) The folderish product derives from ObjectManager. The addable products derive from OFS.SimpleItem.Item, Persistent, Acquisition.Implicit, AccessControl.Role.RoleManager Note that these addable products do have an extra object set inside them. Should this one somehow define copysupport as well? Anybody have any clue why copy and paste is not working? What should I investigate? If this post contains too little information I'll just release my code with this bug next week so people can study it then. :) Regards, Martijn
