How to instanciate and use the instance of a symbol with JSFL

Question

Hi,
I'm a noobie with Flash Pro / JSFL.
I'm looking for a way to instanciate UILoader and use them with JSFL.
I tried to create an empty FLA that contain a UILoader symbol in its library.
With JSFL I open it and add it to the stage.
It works, I have a UILoader instance at 200;200 but I cannot do anything with it. How can I set a size, a new position, a source... ?
fl.openDocument("file:///C|/uiloader.fla");
var loaderIndex = fl.getDocumentDOM().library.findItemIndex("UILoader");
if (loaderIndex != "")
          var loader = fl.getDocumentDOM().library.items[loaderIndex];
          fl.documents[0].addItem({x:200,y:200}, loader);
I would like to create with JSFL a SWF that contain a UILoader placed somewhere with a specific size and specific source. And to inject in the swf some ActionScript to find this added UILoader to dynamically change the source of the image. This source will be finally given from the url. http://myswf.swf?imageSource=xxxxxx.jpg
Is it possible ?
Thank you.

It's a pity !
My problem is I tryed to save a FXG file containing images into a swf that will be able to change images sources dynamically.
To do that, I create an empty FLA document (using JSFL), I import the FXG file into the scene.
If I export my file into SWF in which I have injected this ActionSctipt :
for (var x = 0; x < numChildren; x++)
  var e = getChildAt(x);
  trace(e + " " + e.name +" is "+getQualifiedClassName(e));
I have this trace : [object MovieClip] _IMG_ is flash.display::MovieClip
I think I cannot change the source of a MovieClip using ActionScript. Maybe I'm wrong ?
So I would like to replace these objects (using JSFL) with UILoaders and setting the same x,y,width,height,source and then I will be able to change their sources using ActionScript.
