TypeError: Error #1009: Cannot access a property or method of a null object reference.
   at flare.materials::QuadMaterial/set texture()[Z:\projects\flare3d 2.5\src\flare\materials\]
   at flare.materials::QuadMaterial()[Z:\projects\flare3d 2.5\src\flare\materials\]

the error was raised while creating the Scene3D in function that called at button click

Code: [Select]
private function btn_click(MouseEvent.CLICK):void {
  try {
    var s:Scene3D = new Scene3D(myContainer);

  } catch (err:Error) {
    trace(err, err.getStackTrace());


i found work around through invoking the following code at Main function

Code: [Select]
  // !!!!!
  // just to avoid the scene3d error
  new Scene3D(stage).dispose();

but still not satisfy by that !!!

If you create the scene inside a function, that reference it is likely to be deleted by the garbage collector at some point. Don't do that, create a local class reference instead.
Also if you create the scene on a button click, make sure you're not creating more than one.
