[Paraview] error in Trace

[yaman ozakin]

Hi everyone,
I generate a python script by using Trace for opening a legacy vtk file and
changing the display to "volume".
When I run the script (attached) generated by Trace, the volume has no
transparency. Is this a bug?
Am I doing something wrong?

Regards.

PS: I am using a Paraview on a Win7x64 machine.
