Ok, solved my own problem (eventually) If the Meta Type (found under the Basic management tab of the new class) differs from the Add list name (found in the class' factory) then the class won't support rename and copying operations. I don't know if this should be obvious, but it wasn't for me!

Hi all, What am I doing wrong if my class doesn't support copy and paste or renaming? The class inherits from the basic Zope objects and also (the one) from the Folder class. When I try to copy and paste or rename an instance of my new class, I get the "The object Foo does not support this operation" error. Thanks Etienne
