loadclip in as2.0 class

[P-Sch1FT]

Hi,

I've got a problem using loadclip in a as2.0 imagecontainer class.
It works fine when i place the image container on Stage, but when I attach the clip dynamically with attachmovie, nothing happens. this is what the class looks like. Does anybody have any ideas about this?

when i do a trace in the loadImage function everything seems to be normal, nothing is null or undefined...

class imagecontainer extends movieclip
{
    function imagecontainer()
   {
      target = createEmptyMovieClip("target")   
   }

    function loadImage( file )
    {
          var lc = new MovieClipLoader()
          lc.addListener(this)

          lc.loadclip( file, target )
    }

}

in the .fla file i write something like this:

var im = attachMovie("imagecontainer", "image", 10)
im.loadImage( 'file.jpg' )
