I’m writing a gallery and I have writen custom Tumbnail class that extends Sprite. Each tumbnail has an ID property so I can determine which one is clicked.

I’ve added event listeners to all of them and in handler function tried:

```auto
var target:Tumbnail = Tumbnail(event.targer);

```

so I can get:

```auto
target.ID

```

but I get this error:

```auto
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Sprite@33ce241 to Tumbnail.
	at TumbContainer/::onClick()

```

Anyone know what am I doing wrong?
