[JAVA3D] WakeuponCollisionentry

[BAMBAM]

Hi!

I have spheres and cylinders in my virtual universe and have Wakeuponcollisionentry as 
its condition for its behaviors.

Here are my initialize and processstimulus methods:


    public void initialize() {
        wEnter = new WakeupOnCollisionEntry(shape, 
WakeupOnCollisionEntry.USE_GEOMETRY);
        wExit = new WakeupOnCollisionExit(shape, WakeupOnCollisionEntry.USE_GEOMETRY);
        wakeupOn(wEnter);
    }

    public void processStimulus(Enumeration criteria) {
        inCollision = !inCollision;


        if (inCollision) {
            System.out.println("on collision entry:" + shape);
           //shapeAppearance.setColoringAttributes(highlight);



           Object objC = shape.getUserData();
           System.out.println("prtinting object: " + objC);
           System.out.println("name: " + (((nodeinfo)objC).getname()));
           System.out.println("bond limit" + (((nodeinfo)objC).getlimit()));
---->      // sgp = wEnter.getTriggeringPath();
           System.out.println("prtinting trgpath: " + sgp);
---->>   //node = sgp.getObject();
            //Object objC1 = node.getUserData();
           //System.out.println("name: " + (((nodeinfo)objC1).getname()));
           //System.out.println("bond limit" + (((nodeinfo)objC1).getlimit()));
          wakeupOn(wExit);

        }
        else {
            System.out.println("on collision exit:" + shape);
           //shapeAppearance.setColoringAttributes(shapeColoring);
            wakeupOn(wEnter);
        }
    }

I wanted to get the leaf node (Sahpe3d or geometry primitive) that caused the 
collision of some node in my universe.

The getTrigerringpath method of the Wakeuponcollision entry a null object. Why is 
this? But  my print statement tells me that a collision happened...


Thanks!!
