Fixed! :)
I remembered Ingo saying that he'd removed the transparency attributes from his raster
labels to fix some stuff, where as I'd left them in the org.j3d one but set them to 0f
instead of 1f. I went back and removed the attributes and hey presto I can now switch
the labels off again with
setTransparencySortingPolicy(View.TRANSPARENCY_SORT_GEOMETRY)!
So it appears to be a Raster object with transparency that is within a Switch stays
persistent when switched off if
setTransparencySortingPolicy(View.TRANSPARENCY_SORT_GEOMETRY) is used.
If you think this is still a j3d bug (not just me having no clue how it should work :)
and want an example let me know and I'll put something together.

Thanks for the reply Mark!
I've done a load of debuging to try to narrow down what is happening and I think I now
know.
I can actually traverse the tree fine, I find all the nodes I'm after, dig into them
and get ahold of the apropiet Switch node and can change the current Switch
perfectectly well.
However the switch in question contains a Raster label based on the
org.j3d.geom.RasterTextLabel (with a few fixes that I impremented). When I switch this
off it doesn't disappear from the screen, the switch is at the correct position but
the object appears to be stuck. No error is produced and if I add a second object to
that switch ( i.e. a ColorCube) that object appears and disapears fine but the label
remains.
I'll try to put a small example together now that I know where the bug is.
Cheers,
Jason.

Sounds like it could be a Java 3D bug. The transparency sorting policy
shouldn't affect the application view of the scene graph. Please send us a
test case for investigation.
