Set container spatial on car spatial

Troubleshooting physics

I have a car spatial and a container spatial and after collision I want the container to be set on the car.

Container on agv method

public void loadContainerOnAgv(Node rootNode){
       
 
       /* Under Construction*/
        CollisionResults output = new CollisionResults();
     
        BoundingVolume bv = agv.getWorldBound();

  

//        {
        Containers.container.collideWith(bv, output);
             
       
       //added
       if (output.size()>0 ){
           agvnode.attachChild(agv);
           agvnode.attachChild(Containers.container);
           rootNode.attachChild(agvnode);
           motionControl = new MotionEvent(agvnode,pathagv);

           
            output.clear();
            motionControl.play();
            agvloadready=false;

        }
       else {
         //  agvloadready=true;
       }
       
       
 

       
   //     }
}

Code in main

 @Override
    public void simpleUpdate(float tpf) {
     
        agvtransporter.loadContainerOnAgv(rootNode); 
 
    }

The problem is that after collision the car disappears and the container follows a path but it’s another (non defined) path then the pathagv. The location of the agv node is 0.0.0 , this is intended behaviour?, but I want to set the agv node location to the point on the motionpath where the collision occured.
