Hello everybody,

I am trying to bind a set of radio buttons to an int property. Is there a short way of doing that? Every solution I have found on the Web was quite long.

RadioGroup is a good fit for this, although I have not written any
databinding properties for that widget yet. If you will file a bugzilla
I can get that done within a day or two.

Otherwise you can use SelectObservableValue:

SelectObservableValue select = new SelectObservableValue(int.class);

IValueProperty selectionProp = WidgetProperties.selection();
for (int i = 0; i < buttons.length; i++)
select.addOption(
Integer.valueOf(i),
selectionProp.observe(buttons[i]) );

bindingContext.bind(
select,
BeanProperties.value("myProperty").observe(myModel) );

Thanks a lot Matthew, SelectObservableValue was exactly what I was looking for (I am new to databindings). It works perfectly.
