CASTORGUI::GUIRadio::setChecked() not work

Hello,

The GUI API:

 CASTORGUI::GUIRadio::setChecked(true),

 CASTORGUI::GUIRadio::setChecked(false) is not work.

In addition, would you please  set a group for some related radio buttons?

So, there is one and only one radio button be checked at any time in this group.

e.g.

var myPanel = new CASTORGUI.GUIPanel();

var myRadio_1 = new CASTORGUI.GUIRadio();

myRadio_1.group = 0; // or string name

var myRadio_2 = new CASTORGUI.GUIRadio();

myRadio_2.group = 0;

var myRadio_3 = new CASTORGUI.GUIRadio();

myRadio_3.group = 0;

myPanel.add(myRadio_1);

myPanel.add(myRadio_2);

myPanel.add(myRadio_3);

myPanel.setVisible(true);

Thanks for your reply and help.
