I'm tinkering with a pet project trying to integrate CDI (Weld) with JavaFX2. I don't use FXML for the moment, just building the GUI programatically.

Weld creates my Application class, with all its dependencies, and launches an event that I can answer and call to Application.launch. The problem is that this method creates a new instance of my Application subclass, so all the injections are lost.

I could work around if Application.launch accepted the proper instance and not only its class, but I suppose it's much better if you could subclass some method used to create the instance or even provide an instance builder or factory, so I could use Weld, Guice, Spring or whatever.

I've seen a couples of issues about that in FXMLLoader, related to the controller creation, but I think I'm the first one requesting this at this level. Sorry if it's not the case. :)

Kind regards!
