The action function needs to catch the exception raised 
(InvalidOperation, MissingParameter, etc) and raise
and cherrypy.HTTPError with the error code and message
As generate_action_handler() is only for Resource you need to expose 
this function as follwing:

@cherrypy.expose
def update(self):
     try:
         self.mode.packagesupdate_update()
     except OperationFailed, e:
         raise cherrypy.HTTPError(500, e.message)
