Heya,
I think your problem is that you are not either:
1) clearing the grid before re-populating it
2) removing the last row after a remove has been performed
RadioButton rb = new MyRadioButton("group", radioButtonText);
rb.addClickListener(listener);
scrollBoxGrid.setWidget(i, 0, rb);
except that the last row is now 1 less than it used to be. So I would say just
invoking:
scrollBoxGrid.clear();
before populating it should do the trick ;)
Hope that helps,
