afterFetch()

Hi, my database table for example "names": id int, name varchar, active int

I have something like this in model, yesterday or before yesterday it worked

class Names extends \Phalcon\Mvc\Model
{
    public function afterFetch()
    {
        if($this->id == 5)
        {
              $this->alert = "ALERT"; //alert isn't field in database
        }
    }
}

class IndexController extends \Phalcon\Mvc\Controller
{
   public function indexAction()
   {
       $names = Names::find()->toArrray();
       print_r($names);
   }
}

i got:

Array
(
    [id] => 4
    [name] => Android
    [active] => 1
)
Array
(
    [id] => 5
    [name] => Android
    [active] => 1
)

I need to get

Array
(
    [id] => 4
    [name] => Android
    [active] => 1
)
Array
(
    [id] => 5
    [name] => Android
    [active] => 1
    [alert] => Alert // <----- HERE is what i need to exist
)

only when i add field "alert" to database i can overwrite its value :(

Can you restore previous version?
