Troubleshooting graphics

Can anyone assist me i'm getting an issue at       



  rootNode.lock(display.getRenderer());



I'm attempting a quick conversion from simplegame to a gamstate however their seems to be a slight issue its probably a basic issue but if i comment out the above code i only see red

locking needs to be done in the openGL thread…

hmm i tried adding this and it seemingly worked

    GameTaskQueueManager.getManager().update(new Callable<Object>() {
            public Object call() throws Exception {
                rootNode.lock(display.getRenderer());
                return null;
            }
        });



or should i do below instead?


   Future<Object> future = GameTaskQueueManager.getManager().update(new Callable<Object>() {
            public Object call() throws Exception {
                rootNode.lock(display.getRenderer());
               return null;
            }
        });
        try {
         future.get();
      } catch (InterruptedException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      } catch (ExecutionException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }   
       




it seems to be okay especially after i added

ZBufferState buf = display.getRenderer().createZBufferState();
        buf.setEnabled(true);
        buf.setFunction(ZBufferState.TestFunction.LessThanOrEqualTo);
        this.getRootNode().setRenderState(buf);
