When you invoke this onSubmitSuccess, can you pass in the previousState as well ?

            .then(entry => view.onSubmitSuccess() && this.$injector.invoke(
                view.onSubmitSuccess(),
                view,
                { previousState, $event, entity: this.entity, entry, controller: this, form: this.form, progression, notification }
            ))

because if we pass that, then i can do the redirect to save all list filter parameters, as

        editionView.onSubmitSuccess(['previousState', 'progression', 'notification', '$state', 'entry', 'entity', function(previousState, progression, notification, $state, entry, entity) {
            // stop the progress bar
            progression.done();
            // add a notification
            notification.log(`Element #${entry._identifierValue} successfully edited.`, { addnCls: 'humane-flatty-success' });
            // redirect to the list view
            $state.go(previousState.name, previousState.params);
            // cancel the default action (redirect to the edition view)
            return false;
        }])
