Hmmm ... I have changed the meta type on a few of my zClass based products. I have also changed the "Add list name" in the factory, but I still cannot copy, move, rename etc. Has anybody got a clue?? Zope 2.5.1 but has been upgraded several times from way back. If I don't find a solution I will probably have to refactor into Python Products :-( and I could use that time for something else ... regards Max M
