Personally I prefer to always use objectValues(). Sorting isn't objectXXX()'s problem. It's something you do in your view. objs = list(self.objectValues()) objs.sort(lambda x,y: cmp(x.id, y.id)) It's only a matter of time until you need something more "advanced" and then you shouldn't have to change how you use the objectXXX() iterator. E.g.: objs.sort(lambda x,y: cmp(x.title_or_id().lower(), y.title_or_id().lower())) -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
