Yii-user + RESTFullYii

[djpaoloc]

Hi,
I'm try to implement RESTFullYii with Yii-user module.
This is my LoginController

class LoginController extends Controller
{
    public $defaultAction = 'login';

    /**
     * @var string the default layout for the views. Defaults to '//layouts/column2', meaning
     * using two-column layout. See 'protected/views/layouts/column2.php'.
     */
    public $layout = '//layouts/column1';

// Uncomment the following methods and override them if needed
    public function filters()
    {
        // return the filter configuration for this controller, e.g.:
        return array(
            'accessControl', // perform access control for CRUD operations
            array(
                'ext.starship.RestfullYii.filters.ERestFilter + 
                REST.GET, REST.PUT, REST.POST, REST.DELETE'
            ),
        );
    }

   public function accessRules()
   {
       return array(
           array('allow', 'actions'=>array('REST.GET', 'REST.PUT', 'REST.POST', 'REST.DELETE', 'login'),
              'users'=>array('*'),
           ),
           array('deny',  // deny all users
              'users'=>array('*'),
           ),
       );
   }
    public function actions()
    {
        // return external action classes, e.g.:
        return array(
            'REST.' => 'ext.starship.RestfullYii.actions.ERestActionProvider',
        );
    }

    public function restEvents()
    {
         $this->onRest('post.filter.req.auth.ajax.user', function($validation) {
            return true;
        }); 

        $this->onRest('req.post.user.render', function($data) {
            echo CJSON::encode($data);
            //The $data should contain username and password.
            //Login the user here. Should be easy.
            //Then render a response 
        }); 

        $this->onRest('model.instance', function(){
            return new UserLogin(); 
        }); 
    }  

    /**
     * Displays the login page
     */
    public function actionLogin()
    {
        if (Yii::app()->user->isGuest) {
            $model=new UserLogin;
            // collect user input data
            if(isset($_POST['UserLogin']))
            {
                $model->attributes=$_POST['UserLogin'];
                // validate user input and redirect to previous page if valid
                if($model->validate()) {
                    $this->lastViset();
                    if (strpos(Yii::app()->user->returnUrl,'/index.php')!==false)
                        $this->redirect(Yii::app()->controller->module->returnUrl);
                    else
                        $this->redirect(Yii::app()->controller->module->returnUrl);
                }
            }
            // display the login form
            $this->render('/user/login',array('model'=>$model));
        } else
            $this->redirect(Yii::app()->controller->module->returnUrl);
    }

    private function lastViset() {
        $lastVisit = User::model()->notsafe()->findByPk(Yii::app()->user->id);
        $lastVisit->lastvisit = time();
        $lastVisit->save();
    }

but the sistem return this error

{
   "success": false,
   "message": "Event "UserLogin.onBeforeSave" is not defined.",
   "data":
   {
       "errorCode": 500,
       "message": "Event "UserLogin.onBeforeSave" is not defined."
   }
}

How can I do?
