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. :)
Well, let's start with CopySupport.py. It'll throw above warning in several cases, but the line number in your traceback points to the last case in this method. It first checks if the meta_type of the object copied is addable to the target container (it checks for this with all_meta_types). Then it'll check if the user has permission to add the copied object to this container. One of these two checks fails. You can check this code yourself, it's line 332 up to 369 of CopySupport.py. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
