[Zope-dev] Problem with programmatic copy and paste

[Jonothan Farr]

Actually the copy and paste mechanism should work through Python calls. I don't
see why it wouldn't work from DTML. manage_cutObjects and manage_copyObjects
return the same value that is placed into the cookie. In theory you should be
able to pass this value into the manage_pasteObjects method.

Have you tried it from an external method instead of DTML?
