Sorry for asking that, but are you really sure that you are using CMF 
1.3.1? With my copy, it imports CMFCatalogAware, and CMFCatalogAware 
calls the portal_catalog's index_object() method, which is as follows:


  def __url(self, ob):
        return join(ob.getPhysicalPath(), '/')

  ...

  def indexObject(self, object):
         '''Add to catalog.
         '''
         url = self.__url(object)
         self.catalog_object(object, url)

This is why I wondered about your example with the news item (or 
whatever it is called).

cheers,
