onRollOver - duplicate thumb, xml [AS2]

Hi,

i try use duplicateMovieClip on my thumb image loaded from xml:

Actionscript Code:

...
obj.onLoadComplete = function(trg:MovieClip) 
{
    counter++;
    if (counter<listOfImage.length) 
    {
        MCL.loadClip(listOfImage[counter], listOfTargets[counter]);
    }
    else 
    {
        preloader._visible = false;
    }
    showImage(trg);
    
    trg.num = counter;
    
    trg.onRollOver = function() 
    {
        tc = this.duplicateMovieClip ("trg_clone"+this.num, this.num); // test
        tc._xscale = 200; // test
    }
    ;
    trg.onRollOut = function() 
    {
        //
    }
    ;
    trg.onRelease = function() 
    {
        //
    }
    ;
}
;
...

On normal objects/buttons duplicateMovieClip works fine, but in xml - not. What am I doing wrong?

Quote:

Creates an instance of the specified movie clip while the SWF file is playing. Duplicated movie clips always start playing at Frame 1, no matter what frame the original movie clip is on when the duplicateMovieClip() method is called. Variables in the parent movie clip are not copied into the duplicate movie clip. Movie clips that are created with the duplicateMovieClip() method are not duplicated if you call the duplicateMovieClip() method on their parent. If the parent movie clip is deleted, the duplicate movie clip is also deleted. If you used MovieClip.loadMovie() or the MovieClipLoader class to load a movie clip, the contents of the SWF file are not duplicated. This means that you cannot save bandwidth by loading a JPEG, GIF, PNG, or SWF file and then duplicating the movie clip.
