<br>
Note: visibilty is set to false. This means that the layer will be hidden.<br>

<br>
Note: queryVisible is set to true. This means that hidden layers won't<br>
be queried.<br>
<br>
So the behavior that the control does not issue any request is correct.<br>
Set queryVisible to false, and you will be fine. If it still does not<br>
work, remove the url property from the control config. This will be<br>
taken from the layer and may prevent the control from issuing queries if<br>
different from the layer url.<br>
