The reason for this error is because of the way python methods work. In this case, you are using an *unbound* method, meaning a method that isn't bound to a particular object. Try:

object.manage_editCataloger('newscatalog')

Where 'object' is the CatalogAware object you want to change the Cataloger value on. You could also do:

manage_editCataloger(object, 'newscatalog')

Thanks.. Getting closer.. Now, the traceback actually pops by the manage_editCataloger , so although i don't know exactly what i am talking about here, it seems we are closing in on a solution. (I'd sure love to be one of the guys who help people out, and not only scream helplessly for assistance.) What happens now is that whenever i add a zclass instance i get the following return: Error Type: TypeError Error Value: sequence index must be integer Traceback (innermost last): File /usr/local/funweb/src/python/Zope2/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/funweb/src/python/Zope2/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/funweb/src/python/Zope2/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: RoleManager) File /usr/local/funweb/src/python/Zope2/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/funweb/src/python/Zope2/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: intranet_news_add) File /usr/local/funweb/src/python/Zope2/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: intranet_news_add) File /usr/local/funweb/src/python/Zope2/lib/python/OFS/DTMLMethod.py, line 145, in __call__ (Object: intranet_news_add) File /usr/local/funweb/src/python/Zope2/lib/python/DocumentTemplate/DT_String .py, line 502, in __call__ (Object: intranet_news_add) File /usr/local/funweb/src/python/Zope2/lib/python/DocumentTemplate/DT_With.p y, line 148, in render (Object: intranet_news.createInObjectManager(REQUEST['id'], REQUEST)) File /usr/local/funweb/src/python/Zope2/lib/python/DocumentTemplate/DT_Util.p y, line 329, in eval (Object: manage_editCataloger(intranet_news, 'newscatalog')) File <string>, line 0, in ?
