Dispatching an event via the context

In RL1 I was able to dispatch an event via the context and have it to be picked up and handled accordingly. E.g.

(context as IEventDispatcher).dispatchEvent(new ApplicationEvent(ApplicationEvent.WIRING_COMPLETE));

In RL2 this no longer works. What is the correct "way" to now dispatch to Robotlegs when you only have a handle on the Context?

Thanks

   Hi philostler,

   Inside of Mediators you have access to the shared event dispatcher, and you can use it like this:

   dispatch(new SomeEvent(SomeEvent.SOMETHING_HAPPENED));

   For any other class that needs the dispatcher you’d have to inject it or let the injector instantiate it:
   [Inject] public var eventDispatcher:IEventDispatcher;

   or if you need it in your config class, you can do this:
   eventDispatcher=injector.getInstance(IEventDispatcher);

   eventDispatcher.dispatchEvent(new SomeEvent(SomeEvent.SOMETHING_HAPPENED));

   For this to happen you need to install the EventDispatcherExtension, or to install the MVCSBundle which includes the EventDispatcherExtension as well.

   I've adapted one of your suggestions to work with what I've got...

   context.injector.getInstance(IEventDispatcher);

   Works great. Thanks!
