MediaDisplay’s onUnload of Doom

The MediaDisplay component has an onUnload event to ensure the FLV or MP3 it’s playing is closed before the component goes away. If you, however, attempt to create a movie clip/component with the same name in the same frame (or maybe it’s depth), it won’t work. You must wait a frame because the onUnload keeps a reference to the clip and stays around until the next frame. This caused havoc in a speech preso I was doing for school. I implemented a quick and dirty doLater to ensure I had no issues.

function doLater(obj, meth:Function):Void
{
        if(post_mc == null)
        {
                createEmptyMovieClip("post_mc", getNextHighestDepth());
        }
        var d:Number = post_mc.getNextHighestDepth();
        var ref_mc:MovieClip = post_mc.createEmptyMovieClip("d" + d, d);
        ref_mc.obj = obj;
        ref_mc.meth = meth;
        ref_mc.onEnterFrame = function()
        {
                trace("ref_mc calling");
                this.meth.call(this.obj);
                this.removeMovieClip();
        };
}
