Injection doesn't appear to be working

Hello,

I'm having a bit of a problem getting RL to work, it appears my injection is not working properly. I'm building a Flash application (edit : I've just seen this post - http://knowledge.robotlegs.org/discussions/questions/89-flash-cs4-c... - this might be the cause...), below is how far I've got:

Document Class:
`package
{

import com.myProject.MyContext;

import flash.display.MovieClip;

public class MyMain extends MovieClip 
{
    protected var context : MyContext;

    public function MyMain()
    {
        context = new MyContext(this);
    }
}

} `

Context:
` package com.myProject
{

import com.myProject.controller.StartupCommand;
import com.myProject.model.services.XMLLoader;

import org.robotlegs.base.ContextEvent;
import org.robotlegs.mvcs.Context;

import flash.display.DisplayObjectContainer;

public class MyContext extends Context 
{
    public function MyContext(contextView : DisplayObjectContainer)
    {
        super(contextView);
    }

    override public function startup() : void
    {
        trace("startup");

        injector.mapSingleton(XMLLoader);

        //This Context is mapping a single command to the ContextEvent.STARTUP
        //The StartupCommand will map additional commands, mediators, services,
        //and models for use in the application.
        commandMap.mapEvent(ContextEvent.STARTUP, StartupCommand, ContextEvent, true);

        //Start the Application (triggers the StartupCommand)
        dispatchEvent(new ContextEvent(ContextEvent.STARTUP));
    }
}

} `

StartupCommand
` package com.myProject.controller
{

import com.swatch.model.services.XMLLoader;

import org.robotlegs.mvcs.Command;

public class StartupCommand extends Command 
{
    [Inject]
    public var xmlLoader : XMLLoader;

    override public function execute() : void
    {

// xmlLoader.startLoading();

        trace("*** xmlLoader *** : " + (xmlLoader)); // THIS RETURNS NULL...
    }
}

} `

XMLLoader:
` package com.myProject.model.services
{

import org.robotlegs.mvcs.Actor;

/**
 * @author alexstanbury
 */
public class XMLLoader extends Actor 
{
    public function XMLLoader()
    {

    }

    public function startLoading() : void 
    {
        trace("start loading the xml in");
    }
}

} `

As you can see, I can get into the execute function of the command but it returns null for the injection of the XMLLoader. I am using latest RL .swc

Any ideas?

   Hi,

   What are you using to compile your app?

   Hi Shaun,

   I was using CS4, and realised from reading that thread mentioned in my previous post that the CS3/4 compiler strips out metadata.

   So I have converted my project to use the flex compiler, and am using an asset.swc to access movieclips etc.

   I looked at the XML workaround but it seems a bit longwinded.

   Hi Alex,

   Yes, unfortunately CS3/4 does strip out the metadata, and the XML workaround is quite verbose. Compiling with MXMLC and including assets via SWC files is definitely the recommended approach.
