Model gets injected but it's properties and methods are undefined

Hi there,

This is my first robotlegs project and I have looked through several posts where people seemed to have a similar problem but still haven't found a solution.

In my Context, I am using mapSingletonOf() to map a Service injected into used by StartupCommand and Model injected into and used by PopulateModelCommand.

override public function startup ():void
{

commandMap.mapEvent(ContextEvent.STARTUP_COMPLETE, StartupCommand, ContextEvent);
commandMap.mapEvent(DataEvent.GALLERY_LOADED, PopulateModelCommand, DataEvent);

injector.mapSingletonOf(IBPModel, BPModel);
injector.mapSingletonOf(IDataService, XMLLocalService);

mediatorMap.mapView(Main, MainMediator);
mediatorMap.createMediator(contextView);

super.startup();

}

XMLLocalService gets injected and I can access it's method loadData() no problem at all. See below.

public class StartupCommand extends Command
{

[Inject]
public var service:IDataService;

override public function execute ():void
{
    service.loadData();
}

}

However when I try and use BPModel

public class PopulateModelCommand extends Command
{

[Inject]
public var model:IBPModel;

[Inject]
public var event:DataEvent;

override public function execute() : void
{
    trace("PopulateModelCommand, model=" + model);
    model.test();
    //model.gallery = event.gallery;
}

}

the model gets injected (I get a trace model=[object BPModel] but when I try and access any of the model's properties/methods I get a compiler error PopulateModelCommand.as(23): col: 10 Error: Call to a possibly undefined method test.
model.test();

Both BPModel and XMLLocalService extend Actor. Why can I access the methods in a service but can't in my model? What am I doing wrong?

I am using RL swc 1.3.0. My compiler is set to keep [Inject] and [PostConstruct]. Below is the full stack I am getting when I am trying to compile the project.

mxmlc -load-config+=obj\BPLandingPageConfig.xml -debug=true -incremental=true -benchmark=false -keep-as3-metadata+=Inject -keep-as3-metadata+=PostConstruct -o obj\BPLandingPage634210368560312500

Many thanks for your help in advance.

   Hi Igor,

   It’s a name collision ( var model and package name model ):

   import model.IBPModel;
   and
   [Inject] public var model:IBPModel;

   Try to change the var model to something else, say
   public var bpModel: IBPModel;
   and it will work.

   And don’t call test() in the constructor:
   public function BPModel()
   { test();
   }

   Ondina. Amazing, thank you so much. What was confusing me is that when I was tracing the model I was given the right type model=[object BPModel] which led me to believe I was dealing with the right object and no name collision was happening.

   Btw. When I was calling test() in the constructor it would fire OK as I expected.
