title: WorldWind Java on a Netbeans Platform TopComponent
body: <p>I'm trying to add a layer to WorldWind Java (version 1.2) situated on a Netbeans Platform TopComponent (using netbeans 7.0). 
  The TopComponent is in Editor mode, and for WWJ I  use WorldWindowGLCanvas which  is the single swing component on the TopComponent and it is placed with BorderLayout.CENTER. 
  If I add the layers using the constructor all works well, I can see the layers fine. If I add the layer using swing controls (eg a button) the layer gets added to the layer list but it is not rendered. This happens for both WMS and Renderable layer. 
  Same process on a pure swing application works fine which leads me to believe that the rendering process in WWJ is somehow conflicting with the TopComponent painting. 
  Any help with be greatly appreciated. </p>
