I tried to make a demo of this, but it doesn't seem to work as I'm expecting.

http://www.vtk.org/Wiki/VTK/Examples/ArrayCalculator

I would expect the output to be
0
0
1
or something about like that (depending on the value of sign(0)).

Instead the output doesn't seem to be any different from the input
(still 1, 2, 3).

Dominik, would you mind taking a look and fixing this small example?

Thanks,

David
