[away3d] Problem with BitmapMaterial,

[Flchakir]

hi guys, I really do not understand why it does not work, I just tried
to load a jpeg image,   normal size, and from there I created a Plane
with this BitmapMaterial, then I add the scene, here is my code
simplified and the error it gives me an error : Bitmap Not valid

private function loadNextPlane() {



                        var loaderContext:LoaderContext = new LoaderContext ();
                        loaderContext.checkPolicyFile = true;

                        var imageLoader:Loader = new Loader();

                        imageLoader.contentLoaderInfo.addEventListener( 
Event.COMPLETE,
imageLoaded );
                        imageLoader.load( new URLRequest( (this.projectsListData
[currentIndex] as Project).image ), loaderContext );

                }

                function imageLoaded (e : Event ) : void {

                        var loadedBmp : Bitmap = e.target.content as Bitmap;

                        var bmp:BitmapData = new BitmapData(loadedBmp.width,
                                                        loadedBmp.height,
                                                                                
                true,
                                                                                
                0x00000000
                                                             );

                        createPlane(bmp);



                }
                public function createPlane(bmp:BitmapData):void{
                        var plane:Plane = null;

                        var newWidth:Number = 310;
                        var newHeight:Number = 190;
                        var planeMaterial:BitmapMaterial = null;

                                planeMaterial = new BitmapMaterial(bmp);
                                 planeMaterial.smooth= true;

                                plane = new Plane( {material :planeMaterial 
,width: newWidth,
height:newHeight,segmentsW:4, segmentsH:4});

                                 plane.x=300;


                          // delete the loaded iamge
                            bmp.dispose();

                           plane.extra = {planeIndex : 1, height: newHeight};
                           scene.addChild(plane);
                           planes.push(plane);

                }


shame I'm stuck at the beginning, yet I understand away3d through
every demo, and tutorials

Please help !!!!!
