Problem with wxRadoBox

Hi,
I'm trying to place wxRadioBox on the dialog and
notice couple of issues:

1. Added choices are not reflected n ether design
or preview mode
2. Even though the "Dimension" is set to 5, which reflects
the number of choices added, I can't increase the "Selection"
feld. It drops back to 0.

I didn't yet tried to generate the code, but I hope that
the choices will be saved and the selection will be set
appropriately.

Thank you.
