By refresh, I mean to say that the data store is re-queried.




More clearly, I changed the code (in src/jarabe/journal/listview) from ::

##################################################################
    def refresh(self):
        logging.debug('ListView.refresh query %r', self._query)
        self._stop_progress_bar()

        if self._model is not None:
            self._model.stop()
        self._dirty = False

        self._model = ListModel(self._query)
        self._model.connect('ready', self.__model_ready_cb)
        self._model.connect('progress', self.__model_progress_cb)
        self._model.setup()
##################################################################



TO





##################################################################
    def refresh(self):
        if not self._inhibit_refresh:
            self.proceed_with_refresh()

    def proceed_with_refresh(self):
        logging.debug('ListView.refresh query %r', self._query)
        self._stop_progress_bar()

        if self._model is not None:
            self._model.stop()
        self._dirty = False

        self._model = ListModel(self._query)
        self._model.connect('ready', self.__model_ready_cb)
        self._model.connect('progress', self.__model_progress_cb)
        self._model.setup()
##################################################################


where "self._inhibit_refresh = False", in multi-select mode.

Ajay
