How to click on direct.showutil.Rope

I am trying to make a Rope node ( clickable, but have not had any luck. I have referenced this tutorial ( and the chess sample code, and can get a model loaded from an egg to be picked up by the CollisionRay, but the Rope has not worked. I have tried setting the RopeNode ( setIntoCollideMask(GeomNode.getDefaultCollideMask()), but that was unsuccessful. The underlying RopeNode is generating geometry somehow, so I think it should be possible to detect a collision, but I have no idea how. Any advice? Thanks.
