Buggy source:

  if (rootNode != null) {
    dispose();
  }
  rootNode=new Node("String_Node_Str");
  RenderManager rm=ClientContextJME.getWorldManager().getRenderManager();
  RenderComponent rc=rm.createRenderComponent(rootNode);
  this.addComponent(RenderComponent.class,rc);
  ZBufferState zbuf=(ZBufferState)rm.createRendererState(StateType.ZBuffer);
  zbuf.setEnabled(true);
  zbuf.setFunction(ZBufferState.TestFunction.LessThanOrEqualTo);
  rootNode.setRenderState(zbuf);
  WireframeState wf=(WireframeState)rm.createRendererState(StateType.Wireframe);
  wf.setEnabled(true);
  rootNode.setRenderState(wf);
  if (bounds instanceof BoundingSphere) {
    float radius=((BoundingSphere)bounds).radius;

  }
  Vector3f translation=cell.getWorldTransform().getTranslation(null);
  translation=translation.add(bounds.getCenter());
  rootNode.setLocalTranslation(translation);
