Adding Animation Tutorial Incorrect?

I am just getting started with Haxe/OpenFL having come from a C++ background with no Flash experience.
In the tutorial http://www.openfl.org/learn/tutorials/adding-animation/ I encountered issues when following the code as written in regards to the usage of a container sprite.

The code supplied is:

    var bitmap = new Bitmap (Assets.getBitmapData ("assets/openfl.png"));
    bitmap.x = - bitmap.width / 2;
    bitmap.y = - bitmap.height / 2;
    bitmap.smoothing = true;
    var container = new Sprite ();
    addChild (bitmap);
    container.alpha = 0;
    container.scaleX = 0;
    container.scaleY = 0;
    addChild (container);
    Actuate.tween (bitmap, 3, { alpha: 1 });
    Actuate.tween (bitmap, 6, { scaleX: 1, scaleY: 1 }).ease (Elastic.easeOut);

But this resulted in nothing showing up on screen.
I had to change the code as follows in order to get expected results:

    var bitmap = new Bitmap (Assets.getBitmapData ("assets/openfl.png"));
    bitmap.x = - bitmap.width / 2;
    bitmap.y = - bitmap.height / 2;
    bitmap.smoothing = true;
    var container = new Sprite ();
    container.addChild (bitmap); //Adding bitmap to container instead of to Main.
    container.alpha = 0;
    container.scaleX = 0;
    container.scaleY = 0;
    addChild (container);
    Actuate.tween (container, 3, { alpha: 1 }); //Tweening container instead of bitmap
    Actuate.tween (container, 6, { scaleX: 1, scaleY: 1 }).ease (Elastic.easeOut); //Tweening container instead of bitmap

Thank you! Yes, that was a typo.

I hope you enjoy OpenFL, and please ask if you have any questions :grinning:
