SignalCommandMap isn't triggering commands

Hiya, I've downloaded Joel Hooks' signals / robotlegs source and have made my own project in the same way. For some reason my commands aren't triggering. I've imported as3-signals-v0.5.swc robotlegs-framework-v1.0.3.swc and signals-extension-SignalsCommandMap.swc

I want my LoadXML Signal to be triggered after load, where should I dispatch this? I have tried at the end of the startup function but the mapped Command doesn't execute.

If anyone has any suggestions I'd be very grateful!
Thanks

override public function startup():void

{

    trace("startup");

    //map models
    injector.mapSingleton(XMLService);
    injector.mapSingleton(ApplicationModel);

    //map signals
    injector.mapSingleton(ApplicationDataLoaded);
    injector.mapSingleton(XMLLoaded);


    //signal command map
    signalCommandMap.mapSignalClass( LoadXML, LoadXMLCommand );
    signalCommandMap.mapSignalClass( XMLLoaded, XMLLoadedCommand);
    signalCommandMap.mapSignalClass( ApplicationDataLoaded, SetApplicationDataCommand);


    //map mediators
    mediatorMap.mapView( GroupSelectorView, GroupSelectorMediator );
    mediatorMap.mapView( InfoPanelView, InfoPanelMediator );

    injector.mapSingleton(LoadXML);



}

   What's missing in your code is a Command that's mapped to the ContextEvent.STARTUP_COMPLETE event and the actual dispatching of the event:

   `commandMap.mapEvent(ContextEvent.STARTUP_COMPLETE, StartupCommand);

   super.startup();`

   In this case the event is mapped to a Command called StartupCommand. The super call makes sure the complete event gets dispatched. To dispatch your LoadXML Signal, you can inject it into the StartupCommand and then dispatch it from the execute method.

   If you'd rather avoid events completely, here's an all-Signal way of running your StartupCommand:

   var startup:Signal = new Signal(); signalCommandMap.mapSignal(startup, StartupCommand); startup.dispatch();

   injector.mapSingleton(LoadXML);

   That is going to overwrite the mapping/signal created when you mapped it to the command.

   Thanks Joel and adeldebeer.

   I didn't realise that mapping a singleton of my LoadXML signal would overwrite the assignment in thesignalCommandMap so thanks for that Joel.

   I've also implemented the code suggested by abeldebeer.

   For clarity and in case this is useful for anyone else I have included my code below.

   Thanks again guys :)

   ApplicationContext.as:

   override public function startup():void
   

   {
       trace("startup");
   
       //map models
       injector.mapSingleton(XMLService);
       injector.mapSingleton(ApplicationModel);
   
       //signal command map
       signalCommandMap.mapSignalClass( LoadXML, LoadXMLCommand );
       signalCommandMap.mapSignalClass( XMLLoaded, XMLLoadedCommand);
       signalCommandMap.mapSignalClass( ApplicationDataLoaded, SetApplicationDataCommand);
   
       //map mediators
       mediatorMap.mapView( GroupSelectorView, GroupSelectorMediator );
       mediatorMap.mapView( InfoPanelView, InfoPanelMediator );
   
       //map startup
       commandMap.mapEvent(ContextEvent.STARTUP_COMPLETE, StartupCommand);
       super.startup();
   
   }

   StartupCommand.as:

   [Inject]

       public var loadXML:LoadXML;
   
       override public function execute():void{
           loadXML.dispatch();
       }
