In class A I load content into the Loader object. public class A { var loader:Loader; public function A():void { loader = new Loader(); this.addChild(loader); loader.load(...); } } public class B() { var loader:Loader; public function B():void { loader = new Loader(); this.addChild(loader); } } I need to now assign A's Loader to B's Loader (after the load is complete).
