Root access to method in document class from loaded swf

1

Hello, Im having whta I think is a quite common problem. I recently started migrating form AS2 to AS3 and Im buidling a home made template for all AS3 projects…

I have just loaded portfolio.swf on top of main.sfw. The buttons on portfolio.swf share the same class as the buttons on main.swf

This is the button class:


package com{
    import flash.display.*;
    import flash.events.*;

    
     public class Boton extends MovieClip{
         
        public function Boton(){                
            addEventListener(Event.ADDED_TO_STAGE,init);
        }
        
        private function init(e:Event){
            removeEventListener(Event.ADDED_TO_STAGE, init);
            
            addEventListener(MouseEvent.CLICK,this.onClick);
            addEventListener(MouseEvent.ROLL_OVER,this.onOver);
            addEventListener(MouseEvent.ROLL_OUT,this.onOut);
            
            activaBoton();
        }
        
        public function activaBoton():void{
            enabled=true;
        }
         
        public function desactivaBoton():void{    
            enabled=false;
        }
                
        
        public function onClick(e:Event):void{
            trace("BOTON PULSADO : "+ name);
            //Main.singleton.cambiarSeccion(name); - opcion SINGLETON
            trace(TopLevel.stage);
            TopLevel.root.cambiarSeccion(name);
        }
        
        public function onOver(e:Event):void{
            this.gotoAndPlay("rollOver");
        }
        
        public function onOut(e:Event):void{
            this.gotoAndPlay("rollOut");
        }
        
    }
}

As you can see, when the button is clicked it calls **TopLevel.root.cambiarSeccion(name) , **which is a function in Main.as that handles the change of section …

It works perfectly fine in main.swf, but when I try to compile portfolio.swf (loads on top of main.swf) It throws an error 1061: Llamada a un método cambiarSeccion posiblemente no definido mediante una referencia con tipo estático flash.display:DisplayObject. - 1061: Call to method cambiarSeccion not defined usgin a static reference flash.display:DisplayObject

¿Any ideas on how could I fix this? :h:

Any help will be really really be appreciated, I have already spent many many hours trying to fix this thing …
