[Paraview] paraview3.3.0: Glyph filter ignores ScaleFactor in ascript?

[Robert Cimrman]

Whoops, now I can see what was wrong... I should stop today.

arrows.ScaleFactor = 0.001
instead of
arrows.SetScaleFactor = 0.001

It works now, thanks Sylvester!

BTW. how do I color the glyphs according to their magnitude?
If you happen to have a complete example code with colorbars, opacity
setting, etc. that you could share I would be very happy. :) The public
documentation is a little bit terse (I do not have the manual).

Is it possible to force paraview to report something/raise an error if
one sets an attribute that is not a valid property name? The mistake
that I made is very difficult to detect for a paraview newbie...

cheers,
r.
