Dave,
I am sorry to say this, but it seems like our issues differ a bit. In
my case I was removing from the page a panel which contained some
RadioButtons. Later on I was setting their values, and then putting
the panel that contained them back into the page. The problem I was
encountering was with radio buttons that were grouped together. If
one button in the group was selected and I tried to set a different
one in the same group, then they would both be selected, which was not
supposed to happen. I found that if I put the panel back into the
page first, and then set the values, the groups of radio buttons
worked as they should.
I was trying to recreate what you are talking about wrote the
following code:
public void onModuleLoad()
{
RadioButton radio1 = new RadioButton("group", "option 1");
radio1.setValue(true);
VerticalPanel panel = new VerticalPanel();
panel.add(radio1);
RootPanel.get().add(panel);
}
This worked as expected. The radio button was set. Is this an
accurate representation of your problem?
