Okay I know its bad to answer my own post but I just ran this as an external method, and this tells you what object is in a version without having to wander through the ZMI. Might be a useful function to include on a tab in the Version object? I'll lob it in the collector def find(self): objects = self.ZopeFind(self, search_sub=1) output = [] for url, obj in objects: v = obj.locked_in_version() if v != '' and str(v) != '0': # why do some objects have 0 as a version? output.append(v, obj.absolute_url()) output.sort() output_str = 'Version | Object' for o in output: output_str = output_str + '%s | <a href="%s/manage">%s</a><br>\n' % (o[0], o[1], o[1]) return output_str Cheers. -- Andy McKay.
