Hi!

when you have portal types that are all derived from the same base type 
you want to be able to tag them as belonging to a same given category, 
for instance portlets are all derived from a CPSPortlet.py class and 
'cps_is_portlet' is being used to identify them.

    security.declarePublic('listPortletTypes')
    def listPortletTypes(self):
        """Return the list of all defined portal_types which are portlets

        It means having the 'CPS Portlet' flag
        """
        ttool = getToolByName(self, 'portal_types')
        returned = []
        for id in ttool.objectIds():
            fti = getattr(ttool, id)
            if getattr(fti, 'cps_is_portlet', 0) == 1:
                returned.append(id)
        return returned

how would you do otherwise? use a dummy action called 'isportlet' ?.
