Kelvin:
Thanks for the prompt reply.
>Which version of Java3D are you using ?
We are using Java 3D 1.2.1_03 and the JavaTM 2 Platform, Standard Edition
v1.3.1_01
>What wakeup criteria are use in the custom behavior ?
Here is a code snippet.
****
criterion = new WakeupCriterion[7];
criterion[0] = new WakeupOnAWTEvent(MouseEvent.MOUSE_MOVED) ;
criterion[1] = new WakeupOnAWTEvent(MouseEvent.MOUSE_PRESSED);
criterion[2] = new WakeupOnAWTEvent(MouseEvent.MOUSE_DRAGGED);
criterion[3] = new WakeupOnAWTEvent(MouseEvent.MOUSE_CLICKED);
criterion[4] = new WakeupOnAWTEvent(MouseEvent.MOUSE_RELEASED);
criterion[5] = new WakeupOnAWTEvent(KeyEvent.KEY_RELEASED);
criterion[6] = new WakeupOnAWTEvent(KeyEvent.KEY_PRESSED);
wakeupOn( new WakeupOr( criterion ));

Yes, I did check that. And the public void initialize method is getting
called every time a new VRML world is loaded.

After the new VRML world is loaded, I tried couple of things (as I mentioned
earlier). Here is some code snippet
Canvas3D canvas3D = vrmlDisplayer.getCanvas3D();
View view = canvas3D.getView();
view.stopView();
view.startView();
view.stopBehaviorScheduler();
view.startBehaviorScheduler();
canvas3D.stopRenderer();
canvas3D.startRenderer();
But even then the processStimulus method is not getting called. The only
time it does get called when I manually minimize and maximize the window.
Let me know if you can help in any ways.
Thanks,
Rahul
