Yes, that works fine in Swing...

... but there doesn't seem to be something similar in FX.  Googling
suggests that input validation is currently one the missing pieces in FX
and it seems that right now everybody uses a FocusListener to validate
the input when the control loses focus.

Well, never mind, I've simply stopped using a bidirectional binding with
a number-string-converter and just use

      maxTreffer.bind(Bindings.createIntegerBinding(() -> {
             String txt = txtMaxTreffer.getText();
             try {
                return Integer.valueOf(txt);
             } catch(NumberFormatException ignored) { }
             return maxTreffer.get();
          }, txtMaxTreffer.textProperty()));

Thanks for all suggestions,
Tassilo
