[probably a basic zope question but...] I notice the following idiom in several places, for instance in folder_contents.dtml or folder_rename_form.dtml : > portalish="_.hasattr( obj, 'isPortalContent' ) > and obj.isPortalContent" Does it behave differently from portalish="_.getattr(obj, 'isPortalContent', 0)" Or is it juste "suboptimal" code ? :-) Thanks, Florent Guillaume Nuxeo
