Hi Rob,<br>
<br>
try to use <br>
<br>
<tt>node.disable();</tt><br>
<br>
where <tt>node</tt> could for example be determined via <tt>getNodeById(
String id )</tt> [1] on your tree panel.<br>
<br>
Best regards,<br>
Chris<br>

<div style="font-family: arial,helvetica,sans-serif; font-size:

when the user zooms out greater than zoom level 12. This will
tell the user that the layer is deactivated.</div>
<div style="font-family: arial,helvetica,sans-serif; font-size:

sets the visibility , but when the zoom level is 11, the tick
box is still white and can still be ticked on and off.</div>
