Loader vs Swf

Question

Hi
I have a file named A that is a basic document. Just used to
load another movie named B. If I load the movie B and the movie B
has only something on the Timeline, but no Document Class, all
works great. In the other way, if the document B has a Document
Class (Very basic too), and nothing on the timeline, all works
great. The problem is if I have a Document Class and something on
the timeline, then I get this error. mc_topNav in this case is the
Clip on the Timeline and ca.MyClass is my Documnet Class
ReferenceError: Error #1056: Cannot create property mc_topNav
on ca.MyClass.
at
flash.display::Sprite/flash.display:Sprite::constructChildren()
at flash.display::Sprite$iinit()
at ca.forces.sections::Section$iinit()
This is my code on the main document A
import flash.display.Loader;
import flash.events.*;
import flash.net.URLRequest;
import ca.MyClass;
var loader:Loader;
loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.INIT,
contentComplete);
loader.load(new URLRequest("mySimpleClip.swf"));
function contentComplete(events:Event):void {
addChild(loader);
var myContent:MyClass = (loader.content as MyClass);
myContent.init();
If I comments the 2 last lines :
//var myContent:MyClass = (loader.content as MyClass);
//myContent.init();
It works, else there is the error message.
Just like I can have a Class Document while I don't call any
methods of it when there is a Clip on the timeline.
Any Idea.
