Ok
Need some help as I get up to speed with RL.

1
To start, am I correct in thinking of Context as Facade in PureMVC?

2
Is a Startup Command necessary?

3
How would I translate the following (from Application facade and StartUpCommands in PureMVC) in my ApplicationContext file?

//CODE START //StartupCommand start facade.registerProxy(new DataProxy(app));

        facade.registerMediator(new StageMediator(stage));
        facade.registerMediator(new ApplicationMediator(app));

//StartupCommand end //ApplicationFacade start

override protected function initializeController():void

    {
        super.initializeController();

        registerCommand(Constants.CMD_STARTUP, StartupCommand);
    }

    public function startup(stage:Object):void
    {

        sendNotification(Constants.CMD_STARTUP, stage);
    }

//ApplicationFacade end

   Hi There,

   Your formatting got a bit screwed up there, but I think what you're looking for is ContextEvent.STARTUP_COMPLETE, for example:

   package foo.bar
   {
       import foo.bar.command.BootstrapApplicationCommand;
       import org.robotlegs.base.ContextEvent;
       import org.robotlegs.mvcs.Context;
       import flash.display.DisplayObjectContainer;
   
       public class BarContext extends Context 
       {
           public function BarContext(contextView : DisplayObjectContainer = null, autoStartup : Boolean = true)
           {
               super(contextView, autoStartup);
           }
   
           override public function startup() : void 
           {
               // Executes BootstrapApplicationCommand as soon as this method completes.
               commandMap.mapEvent(ContextEvent.STARTUP_COMPLETE, BootstrapApplicationCommand, ContextEvent, true);
   
               // Causes the ContextEvent.STARTUP_COMPLETE to be fired.
               super.startup();
           }
       }
   }
   

   To answer your questions directly; most people are content with putting their Command Mappings, Mediator Mappings and Injector Mappings into their Context's startup() method. However, I personally prefer to have a Bootstrap Command which itself calls a chain of Commands to get things setup and ready to roll.

   Jonny.
