After some reading of j2me documentation, is clear that the exclusive-choice always has a selected element at any time. What I need, is an exclusive-choice group with not initial selection. It looks senseless but for what I need it for it makes sense. On the first time it appears on screen the control shows all it's items but with no selection won't influence or bias a decision making.
I was wondering if someone has implemented an exclusive-choice control with all items unselected on its first shown.
