title: struts 2 radio button display issue
body: <p>I want to display data under columns cID, cName and cStatus with the first column displaying a radio button. cList is a list of Value Objects(VO=(cID,cName,cStatus)).
  If i select a radio button in front of a record(cID,cName,cStatus) then cIdDetails should be set as the value of cID. 
  By the following code, the value of cIdDetails is set correctly.</p>
  
  <pre><code>        &lt;s:iterator value="cList"&gt;
              &lt;tr&gt;
                  &lt;td width="1%"&gt;&lt;s:radio theme="simple" name="cIdDetails"
                      list="cID" label="&amp;nbsp;"
                      onclick="details()" /&gt;&lt;/td&gt;
                  &lt;td width="20%"&gt;&lt;s:property value="cID" /&gt;&lt;/td&gt;
                  &lt;td width="59%"&gt;&lt;s:property value="cName" /&gt;&lt;/td&gt;
                  &lt;td width="20%"&gt;&lt;s:property value="cStatus" /&gt;&lt;/td&gt;
              &lt;/tr&gt;
          &lt;/s:iterator&gt;

  <p>The only problem is that i dont want to show any label for the radio button. 
  Above code sets the label as cID and displays it as label of radio button.</p>
  
  <p>Required Output</p>
  
  <pre><code>                cId          cName          cStatus
   radiobtn1      ID1           ABC           Single
   radiobtn2      ID2           XYZ           Married
  </code></pre>
  
  <p>Observed Output</p>
  
  <pre><code>                   cId          cName          cStatus
   radibtn1 ID1      ID1           ABC           Single
   radibtn2 ID2      ID2           XYZ           Married
