[away3d] plane click event

[Lucas Guilherme]

Hello,

I'm using this code to get clicked event in a plane

myPlane.addOnMouseDown(planeMouseDown);

function planeMouseDown(event:MouseEvent):void {
    trace("clicked");
}

and didn't work.
When I put the same code for a RoundedCube for example, works.

Any idea?

BR,
Líbiny
