im one of my classes i am trying to call a method from its parent class, but i am getting an error:

```auto

if(parent){
parent.deactivatePanels();
}

1061: Call to a possibly undefined method deactivatePanels through a reference with static type flash.display:DisplayObjectContainer.

```

(parent as myClassName).deactivatePanels();
