Does the use of ObservableList in JavaFX go against Model-View-Controller separation?

Question

I am attempting a study of JavaFX because I want to use it as the GUI of my program. My question is essentially a conceptual one:

To date my program is mostly the \"

I disagree that using an ObservableList in your "model" class violates MVC separation. An ObservableList is purely data representation; it is part of the model and not part of the view. I (and others) use JavaFX properties and collections in model representations in all tiers of my applications. Among other things in there, I point out how I use JavaFX properties that are (or can be, at least) bound to JSF. (I should mention that not everyone agrees with the approach of using FX properties on the server side; however I don't really see any way to make the argument that they are somehow part of the view.)

Also, if you do

List myNonObservableList = ... ;

ObservableList myObservableList = FXCollections.observableList(myNonObservableList);
myObservableList.add(new MachineMonitor());

the observable list is backed by the non-observable list, so the change occurs in myNonObservableList too. So you can use this approach if you prefer.
