Noone has an idea?
To elaborate, when not using bindings, the default behavior of text fields with a number formatter is that when a user tries to enter "abc" in it, the text field refuses to lose focus and makes a beeping sounds. However, when the text field's value binding has been set, a sheet is shown, which I think is a bad user experience. In fact it would be even better to just disallow entering of invalid characters in the first place. But such a method would have to work even if the text field's value binding is set.
