OK. I've solved it:
public class SpaceTravelBehavior extends ViewPlatformBehavior
{
// private TransformGroup targetTG; <- this shouldn't be here since
it's already a protected field in ViewPlatformBehavior.
That is what apparently caused the hickups. I just wonder why it had such
an inconsistent behavior (no pun intended). As I wrote; about every other
run would fail - odd.

Hi,
I don't mean to interrupt your Java 3D/Xith/JOGL discussion, but I'm having
a curious problem with my behaviors. I'm using one behavior to move the
view through space (an extension based on KeyNavigatorBehavior), but about
every other time (or so) I run it, it freezes - no behaviors are called
anymore. If I resize the window, the canvas is redrawn as it should be -
only no movement. If I run it in debug mode, there is _no problem_. At this
point I should say that I'm using JBuilder 9 personal.
Does anyone have any experience with such problems? Or maybe suggestions as
to what the problem is?
Could it be a memory issue? I only use a PointArray of 20 and 20 spheres
with 36 subdivisions.
I've enclosed the processStimulus in a try-catch, but that doesn't seem to
be it.
I know that it is not all-encompassing, but here's a bit of the code:
public void processStimulus(Enumeration enumeration)
{
try {
float deltaTime=(float)timeWarp*(float)getDeltaTime
()/1000f;
targetTG.getTransform(viewTransform);
velocity.z=10000*Constant.c*(10000);
deltaPosition.scale(deltaTime, velocity);
position.add(deltaPosition);
// System.out.println(position.z);
// oldPosition.set(position);
viewTransform.set(position);
targetTG.setTransform(viewTransform);
} catch (Throwable e)
{
e.printStackTrace();
}
wakeupOn(w);
}
Any help appreciated.
Regards
