I have an application where some of my Products are Python based and others are zClasses. As far as I remember it was possible to copy paste the zClass based objects when I first wrote the app. But somewhere along my upgrades I seem to have lost the ability to copy/paste those objects. My Python based products can be copied nicely. Has anybody got an idea as to why ??? regards Max M --------------------------------------- Error: "The object /ProjektNet/ does not support this operation" Traceback (innermost last): File C:\zope\zope251\lib\python\ZPublisher\Publish.py, line 150, in publish_module File C:\zope\zope251\lib\python\ZPublisher\Publish.py, line 114, in publish File C:\zope\zope251\lib\python\Zope\__init__.py, line 159, in zpublisher_exception_hook (Object: 2_semester) File C:\zope\zope251\lib\python\ZPublisher\Publish.py, line 98, in publish File C:\zope\zope251\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: manage_pasteObjects) File C:\zope\zope251\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: manage_pasteObjects) File C:\zope\zope251\lib\python\OFS\CopySupport.py, line 144, in manage_pasteObjects (Object: 2_semester) File C:\zope\zope251\lib\python\OFS\CopySupport.py, line 373, in _verifyObjectPaste (Object: 2_semester) Copy Error: (see above) RoboVenture ProjektNet Undervisere Kursusplan Emner Materiale Diskussion Kursister Skema Undervisere Kursusplan Emner Materiale Diskussion Kursister Skema Evaluering Max M 1 Undervisere Kursusplan Kursister
