AS3 Flash - Adding movieclip to stage with Actionscript not working

For some reason unknown to me, I am unable to add a movieclip to stage or my document class.

This is what I have:

var testShard:blockshards = new blockshards();
addChild(testShard);

Nothing happens but the code for blockshards is executed (I see it in output).

When I manually add it in the .fla file it works.

Does anyone know why? When I replace blockshards with another movieclip it works fine.

Here's my blockshards.as:

package  {
    import flash.events.Event;
    import flash.display.MovieClip;
    public class blockshards extends MovieClip{
        var framesToDie:uint = 30;
        var xspeed:Number = 0;
        var yspeed:Number = 0;
        public function blockshards() {
            addEventListener(Event.ENTER_FRAME, onEntFrm);
            xspeed = 2 - Math.random() * 4;
            yspeed = -5;
        }
        public function onEntFrm(e:Event){
            framesToDie--;
            if(framesToDie <= 0){
                this.parent.removeChild(this);
                removeEventListener(Event.ENTER_FRAME, onEntFrm);
            }
            alpha -= 0.03;
            x += xspeed;
            y += yspeed;
            yspeed += 0.2;
            xspeed *= 0.98;
        }
    }

}

You should not execute code directly on your display objects constructors, it is always a better idea to place a check for the sage first, other ways, weird things happen.

public function blockshards() {
     if ( stage ) _init( );
     else addEventListener(Event.ADDED_TO_STAGE, _init );
}

private function _init( e:Event = null ):void {
    removeEventListener( Event.ADDED_TO_STAGE, _init );
    addEventListener(Event.ENTER_FRAME, onEntFrm);
    xspeed = 2 - Math.random() * 4;
    yspeed = -5;
}

Same thing on your document class' constructor.

I moved the code to another function and it worked somehow without changing anything to do with blockshards.. very weird

There is nothing drawn in or attached to your movieclip. Your clip will be there but shown empty!

Edit: Apparently this is already known by you. And I don't know Flash :-) But here is a link that gives you a step by step description of exporting movieclips for ActionScript:

Hope you have used linkage Properties to create the blockshards class.

So it may be registration point problem. So please check the registration point of the MovieClip.
