So you may have two solutions to handle this in the "removeSource" method : 1. sources = self.source sources.remove(source) self.source = sources 2. self.source.remove(source) self._p_changed = True _______________________________________________ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
