from PureMVC to RobotLegs...bestPractices for startup

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

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

Is a Startup Command necessary?

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


        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:

        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.

    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.
