I'm having a bit of a problem with getting signals to work properly. I have the latest RL, signals and CommanMap Extension.

Relevant code in SignalContext:

signalCommandMap.mapSignalClass(XMLLoadedSignal, XMLLoadedSignalCommand);

Relevant code in XMLLoader :

var xmlLoaded : XMLLoadedSignal  = new XMLLoadedSignal();
xmlLoaded.dispatch();

XMLLoadedSignal:

public class XMLLoadedSignal extends Signal {
    public function XMLLoadedSignal() {
        trace("signal xml loaded");
    }
}

XMLLoadedSignalCommand :

public class XMLLoadedSignalCommand extends SignalCommand 
{
    override public function execute() : void
    {
        trace("command xml loaded");
    }
}

I get the first trace "signal xml loaded" but not the second trace("command xml loaded") - it seems the signal is not executing the command. Is there something fundamental I am missing here? Is there anything else I need to set up?

Thanks

   Never mind, that's twice I've found the answer as soon as I write out the question!

   I was not injecting the Signal into the XMLLoader class, I was creating a new instance of it which was not mapped.

   Here is the relevant code for anyone like me who is a bit dim :P

   public class XMLLoader extends Actor 
   {
       [Inject]
       public var xmlLoaded:XMLLoadedSignal;
   
       public function XMLLoader()
       {
           super();
       }
   
       public function loadingComplete() : void 
       {
           trace("start loading the xml in");
           xmlLoaded.dispatch();
       }
   }
