Swap button doesn't swap radio group values

[andlehma]

<lineEdit id="pName1" x="70" y="70" width="160" height="20" dataSet="players.csv">Player Name 1</lineEdit>
  <radioGroup id="player1Status">
    <radioButton x="240" y="70" width="60" height="20" value="alive">Alive</radioButton>
    <radioButton x="300" y="70" width="60" height="20" value="dead">Dead</radioButton>
  </radioGroup>
  <lineEdit id="pName2" x="70" y="100" width="160" height="20" dataSet="players.csv">Player Name 2</lineEdit>
  <radioGroup id="player2Status">
    <radioButton x="240" y="100" width="60" height="20" value="alive">Alive</radioButton>
    <radioButton x="300" y="100" width="60" height="20" value="dead">Dead</radioButton>
  </radioGroup>
  <button type="swap" x="70" y="30" width="80" height="20" id="swap1" swapSet1="pName1, player1Status" swapSet2="pName2, player2Status">swap</button>

When I press the stop button, the player names swap, but not the radio groups
