Hi,

I use appearance to turn on and off my object texture mapping. I am using
View.setTransparencySortingPolicy(View.TRANSPARENCY_SORT_GEOMETRY) to
sort
the transparent obj.

The error I got as below is after I turn off the texture mapping and
doing
more navigation.

java.lang.NullPointerException

        at javax.media.j3d.J3dThread.run(J3dThread.java:250)

I cannot find more information on the error. There may be something
that I
am not aware of.  I was wondering if any one had the similar situation
can
give some help.

Thanks much!
Lan
