[T5] RadioGroup and varible numbers of radio buttons

[ma...@j-b-s.de]

Hi!

I have a problem to handle a radiogroup having a variable number of radio buttons created within a loop.
The 'tml' looks basically like the following code snippet:

<t:radiogroup t:id="addressSelector">
   <t:loop source="addresses" value="loopAddress">
      <tr>
          <td><t:radio t:id="radio" value="${loopAddress.userId}"/>${loopAddress.userId}</td>
          <td xml:space="preserve">${loopAddress.firstName} ${loopAddress.lastName}</td>
      </tr>
   </t:loop>
</t:radiogroup>

this works just fine.

After adding a additional radio button outside the loop Tapestry complains that the component with the id "radio" already exists?

<t:radiogroup t:id="addressSelector">
   <t:loop source="addresses" value="loopAddress">
      <tr>
          <td><t:radio t:id="radio" value="${loopAddress.userId}"/>${loopAddress.userId}</td>
          <td xml:space="preserve">${loopAddress.firstName} ${loopAddress.lastName}</td>
      </tr>
   </t:loop>
   <td colspan="2"><t:radio t:id="radio" value="NEW ADDRESS"/></td>
</t:radiogroup>

What is the difference to the loop?
So as a workaround I added an empty entry to the address list and preserved the layout by using <t:if> blocks but I really do not understand why this is not working.

Any ideas?

Thanks in advance

Jens

You use the id "radio" 2 times in the same tml page. That's not allowed.
