Stop Using PropertyValueFactory

PropertyValueFactory is an obsolete convenience method designed to eliminate boilerplate. We don’t don’t need it any more now that we have Lambda expressions.

JavaFX Anti-Pattern: The Dispatch EventHandler

The “Dispatch EventHandler”. For some reason I see this in examples on the web all over the place, I think because it’s a technique that seems to integrate with FXML. The idea is that you create a single EventHandler and you invoke it from all of the Buttons (or whatever) on your GUI. In that EventHandler, you check the passed Event and run different code depending on which Button triggered it.

It’s a bad approach that adds complexity to your code and returns you nothing. In this article you’ll see how this approach fails, and how to properly write EventHandlers in a clear and simple way.
