The myth of using Scala as a better Java

Off the top of my head: misses some UI elements / widget types (spinner / numeric entry). UI bindings require a lot of manual converters instead of doing conversions that p.e. WPF does out-of-the-box (like double to string when using a text box; principle of least surprise).

And (the worst) it's not conceptually compatible to the model classes (abstract tree model) that almost every UI framework (including Swing) provides. Instead, tree nodes have to be manually instantiated).

You can use String.valueOf, but usually don’t want to do that. And how do you want to represent the float? With Scientific notation, Engineering notation, or purely decimal? This is not simple.

Or you use the FXML bindings for creating them from XML?
