Puzzling! Code works on FLA but not in Class Package!

Hi,

This is really puzzling me!
I have this simple code in FLA:

var myclass:Class = getDefinitionByName("clsGirlWalking") as Class;
var mcPerson:MovieClip = new myclass();
addChild(mcPerson);

OK, so it DOES work, that is, the mc is instantiated in stage - great!

However, if I put the very same code in a class package:

package
{
    import flash.display.MovieClip;
    import flash.utils.getDefinitionByName;

    public class sgt extends MovieClip
    {
        public function sgt():void
        {
            var myclass:Class = getDefinitionByName("clsGirlWalking") as Class;
            var mcPerson:MovieClip = new myclass();
            addChild(mcPerson);
        }
    }
}

And call it from my FLA with:

import sgt;
var mysgt:sgt = new sgt();

Then it DOESN’T work!

PS: I can trace the new created mc in the output window, but it simply doesn’t show up in the stage!!!

What am I missing here?

Thanks!
