FXML, Presentation Model & bi-directional binding

The only thing you have to do is to write a controller and put
myTextBox.textProperty().bindBidirectional(dataModel.textProperty()); into
the initialize method. It's way less convenient than it could and should be
but at least that gets you bidirectional binding. For a working example
featuring a calculator that can add 4 bits done with bidirectional binding
properties only (+ some FXML) please have a look at
you can find both the code and the talk (in the downloads tab) of a
talk of mine where I compared FX to the presentation model of WPF. The
slides might be worth looking at because they summarize my findings in
surprising FXML binding syntax that are scattered in this mailing list

Hope this helps!
