Hi,
I tried option 'A' however, the radio button in the table is still not
selected when the page is rendered.
I tried calling:
tableSelection.invert(getContactMethod());
or
tableSelection.add(getContactMethod());
however, it does not work. By debuging, I can see that the object is in the
set, however nothing is selected in the UI.
