Assign variant value to radio-button in layout

Hi all,

Have radio buttons in a group and they work fine as long as I pick/assign their value (checked/unchecked) on their event.

I have to assign value (check or uncheck) to them on selection of a variant depending upon whether they have been checked in variant or not.

The problem is, suppose I have two radio button A and B.

Now user selects radio-button B and then selects variant. In variant, radio-button A is checked.

At this point A must be 'X' and B should be cleared.

When i debug and check their value, its correct ( A is checked and B is clear) . But in layout both A and B are shown checked.

How sould I make sure that values in layout are also correct?

Thanks
