I have a rich:dataTable listing data rows with a radio button for each row, but these radio buttons should belong to a single radio button group so only one row can be selected from these radio buttons. However, when I use the following code, the radio button for each row belongs to its own radio button group, please help figure out some approach to have all rows' radio buttons belong to a single radio button group. Thanks.
That's just how JSF works, every row is its own group.
You can use JavaScript, first go over all the radio buttons and uncheck them and then check the newly selected.
