Could FXML use an interface and dynamic proxy for the passive view interface?

>> Which got me thinking. Can't we have FXMLLoader use dynamic proxies to allow the FXML file to refer to a passive view interface rather than a concrete controller implementation? That at least would allow for the "Passive View" design pattern to apply extremely cleanly. It still would mean, from the developer's perspective, 2 classes instead of 1 (an interface for the view and a controller which talks to that interface). I would have to think through this a little more (I guess the controller is still required, so that the FXML document has something to call for event handlers and such, but that the controller would only talk to the view via this Passive View interface rather than by grabbing nodes and binding things directly??)

I think this covers the ControllerFactory -- ie delegate controller construction to the developer -- but is separate from dynamically generating an implementation of a Passive View interface.
