In CopySupport.py CopyContainer._verifyObjectPaste is called by manage_renameObject with a REQUEST object passed. If REQUEST is None in manage_renameObject (the default when not called interactively) _verifyObjectPaste tries to access a user=REQUEST.get('AUTHENTICATED_USER', None) in line 326 (I have no CVS, so this is the std 1.10.2 distribution). Since REQUEST is None an AttributeError is thrown. * * * What I was trying to do is to customize the automatic renaming of object ids (if pasted) via an overloaded _postCopy. I don't know how to solve the above authentication problem (at least as intended) other than by passing the REQUEST object over to _postCopy. Ideas anyone? Stefan
