Using a simple shell swf loader in a puremvc app

[eco_bach]

Can someone calrify how I would use a simple shell loader as outlined in Lee Brimelows tutorial

As I understand it, everything in a PureMVC app starts with the startup command, called via your main document class via application facade.

But using Lee Brimelows shell loader technique requires at a minimum 2 swfs, your preloader shell, and the main application swf you are loading.

Where would the following code go
ApplicationFacade.getInstance().startup( this );

in your preloader 'shell' swf (only called after your main swf has loaded),
OR
in your main application swf?

I think perhaps the answer is simply to ensure your main content swf has a stage reference BEFORE you call the startup command

So in you main swf
addEventListener(Event.ADDED_TO_STAGE,onadded);
trace('BEFORE onadded stage==='+ stage);


function onadded(e:Event):void{
   ApplicationFacade.getInstance().startup( stage );
   trace('AFTER onadded stage==='+ stage);
   
}
