you are using the SAME id for several components in ONE component tree.
false:
<win id="win1">
<button id="btn1" />
<button id="btn1" /> <!-- throws error 'Not unique ID ... -->
</win>
better:
<win id="win1">
<button id="btn1" />
<button id="btn2" />
</win>
better:
<win id="win1">
<win id="win2">
<button id="btn1" />
</win>
<win id="win3">
<button id="btn1" />
</win>
</win>
Look here: ID space
best Stephan
