Hi Emanuel,
The workaround and new API apply when several
behaviors wakeup EVERY frame. i.e. several behavior
use wakeupOnElapsedFrame(0) and we need to order them
appropriately.
However in your case there is two behaviors,
wakeupOnElapsedTime(10) which postId(0) to trigger another
wakeupOnBehaviorPost() so above things will not apply here.
Besides, I'm not sure why you need to get
SchedulingInterval back and do different things,
if you are really doing this in single behavior it should be
viewTransform.get(viewTranslation);
StarsTransform.setTranslation(viewTranslation);
StarsTransformGroup.setTransform(StarsTransform);
viewTransformGroup.setTransform(viewTransform);
instead of
if(getSchedulingInterval()==1)
{
viewTransform.get(viewTranslation);
StarsTransform.setTranslation(viewTranslation);
StarsTransformGroup.setTransform(StarsTransform);
}
else
{
viewTransformGroup.setTransform(viewTransform);
}

Hi Kelvin
Check out evaluate of bug
4332793 -
View transform & object transform not synchronize in a single behavior
I already found this bug in database before, but it is not exactly what i
need.
In the description of the problem in the bug above two behaviors are
involved
where both should be executed in the same time.
But ok, i tracked it down to find the possible soultion (forcing the order
of first running the interpolator and after that running the camera-behavior
by setting the sheduling intervalls).
So i modified the testcase (in a IMHO strange way), ensuring that my object
transform
is executed before the view-transform.
I've done this with another two behaviors wich react on the same stimuli
(WakeupOnBehaviorPost) and so wake up the same time.
These behaviors got sheduling-intervalls to reflect their priority (first
update transform of StarsTransformgroup and secondary update the
view-transformgroup).
BUT same problem as before: rendered frame does'nt shows up both transforms
:(
the following is some of the code i produced (unchanged parts cut out):
plz have a look, its short ;)
