[Zope] CatalogAware PropertyManager

Hi! I wrote a custom CatalogAware object class inheriting from PropertyManager. I'm managing the properties with the regular PropertyManager form (manage_propertiesForm) but I'd like the propertymanager to call reindex_object() each time I modify something. I suppose that the quick'n dirty solution is adding reindex_object() at the end of the manage_editProperties method. But I don't know if there is a cleaner solution or if it will badly affect the rest of objects using PropertyManager... Any hint? Thanks Gari
