[away3d] Error in LightPrebaker

[Jose]

I have found a problem in LightPrebaker.as

                        function setVertexColor(d:Vector3D, n:Vector3D, 
colr:int, colg:int,
colb:int):Array
                        {
                                var dl:Number;
                                var factl:Number;
                                for(j = 0;j<_aLights.length;++j){
                                        dl = 
d.subtract(_aLights[j].lightposition).length;
                                        percentFalloff =   
(_aLights[j].lightfalloff- dl)/
_aLights[j].lightfalloff;
<------------------------------->     lightFactor =
_aLights[j].lightposition.getAngle(n);  <----- lightposition is a
Vector3D?

                                        if(percentFalloff > 0 && dl 
<_aLights[j].lightfalloff){
                                                factl = 
lightFactor*percentFalloff;
                                                colr += _aLights[j].lightR 
*factl;
                                                colg += _aLights[j].lightG 
*factl;
                                                colb += _aLights[j].lightB 
*factl;
                                        }
                                }

                                return [colr, colg, colb];

                        }

Throws error with getAngle(). Thanks
