another EventDispatcher is null

first time I'm implementing robotLegs.
I followed the screencast from John Lindquist but I recieve the follwing error

at org.robotlegs.base::EventMap/mapListener()
at com.example.view::CategoryViewMediator/onRegister()

When I trace the eventDispatcher in my mapListener, it outputs null.
When I say export to SWC in my publish settings it all works fine.
But now I'm stuck, what's going wrong? I've read through the commen problems post, but no help.
I'm using the swc files for Robotlegs.

If you need more info, pls let me know.
this is my code for the viewMediator:

public class CategoryViewMediator extends Mediator {

    public var categoryView:CategoryView;

    override public function onRegister() : void
        eventMap.mapListener(eventDispatcher, GreetingEvent.GREET, onGreet);
        dispatch(new GreetingEvent(GreetingEvent.REQUEST_GREETING));

    private function onGreet(event:GreetingEvent) : void

    Hi Vic,

    I'm assuming you're using the Flash CS3/4/5 IDE?

    You have to keep 'export to swc' ticked as otherwise Flash won't include the metadata for the [Inject] tags, and so all your eventDispatchers and other injected values will be missing.

    yes, I'm using CS5.

    Ah ok, so the export to SWC must be checked.
    Thought that wasn't necessary.

    It's necessary because only with export to SWC metadata tags like [Inject] are preserved. If not they're ignored by the compiler. That's all
