[Netbeans Node API] Nodes don't refresh recursively

So Netbeans has the Nodes API to display it's hiearchic structures like you see the SceneGraph in the Scene Explorer.

Now we have that "AbstractSceneExplorerNode" which is the Base-Class to many Nodes.
It features a refresh method which contains the following:

//TODO: refresh does not work
public void refresh(boolean immediate) {
   if (jmeChildren instanceof JmeSpatialChildren) {
      ((JmeSpatialChildren) jmeChildren).refreshChildren(immediate);
   }
}

The Problem here actually is, that those jmeChildren itself don't seem to trigger it's nodes.
I tried to add the following code, but for some reason, the children don't seem to have any nodes attached to. I don't have the time to work into the Nodes API again, though.

Maybe you can read everything in the Commits regarding the MotionEvent Implementation, maybe those update as they should. They also use the Parent/Children Stuff, but it's not JmeSpatialChildren, of course.

for (Node n : nodes) { // TODO: Why is nodes always empty? What about the Children's Children?
  if (n instanceof AbstractSceneExplorerNode) {
     ((AbstractSceneExplorerNode)n).refresh(immediate);
  }
}

(JmeSpatialChildren:refreshChildren)

Ohh, and the AnimationControl Stuff has the same API regarding Children and Nodes

Start with AbstractSceneExplorerNode.refresh(boolean) and JmeSpatialChildren.refreshChildren(immediate), then compare the Parent/Children handling in the MotionEvent implementation. Also inspect the AnimationControl children API mentioned in the issue. Done means scene and animation child nodes refresh recursively when their contents change.
