Problem with finding which behavior is loaded by a model

I wrote this peace of Code in AppController.php's beforeFilter() method :

       if (isset($this))
         if (isset($this->modelClass))
           if (isset($this->{$this->modelClass}))
             if ($this->{$this->modelClass}->Behaviors->loaded('Translate'))
                $this->{$this->modelClass}->locale=$locale ;

but when there is a Controller with no model or a simple plugin like dashboard which no need to have a model this error will appear:

Fatal Error

Error: Cannot access empty property
File: ..\lib\Cake\Controller\Controller.php
Line: 437

It is going to made me crazy!
