Inject

Hi,

I am pretty new to robotlegs. I am trying to inject a RemoteObject into my service. I am patterning my design off of Joel's example on GitHub [ https://github.com/joelhooks/robotlegs-examples-UnionPlatformChatCl... ]. For some reason the injection never happens, so when my service tries to access the remote object. I of course get a 'Cannot access a property or method of a null object reference.' I have verified that I am creating an actual Remote Object and mapped it as such: injector.mapValue(RemoteObject, remoteInst, "ReportViewerSvc"); This injector statement is defined in a command invoked from my own application startup event. I am also using your modules framework if that makes any difference.

Here is a code snippet of my service code:

public class ReportViewerService extends ModuleActor implements IReportViewerService {

    public static const DESTINATION:String = "ReportViewerSvc";

    [Inject(name="ReportViewerSvc")]
    private var dataService:RemoteObject; 

        public function ReportViewerService() {
            super();
        }

}

I appreciate any help that you can provide.

   How are you instantiating your service? If it is mapped as a
   singleton, it should get injected into. If, on the other hand, you're
   creating it manually, you have to either use
   var myService : ReportViewerService = injector.instantiate(ReportViewerService);
   or
   var myService : ReportViewerService = new ReportViewerService();
   injector.injectInto(myService);

   It is mapped as a singleton. Here it is :
   injector.mapSingletonOf(IReportViewerService, ReportViewerService);

   Ah, I didn't look close enough: You have to make the var public for
   the injector to be able to see it. That's a restriction Flash imposes
   which we can't work around.

   Ah, that was it. I should have tried that. Thanks for your help.
