[Paraview] ParaView + Python: WriteImage screenshots broken?

[Nico Schlömer]

What do you mean by "v"?

I took a wild guess and did

============== *snip* ==============
from paraview.simple import *
reader = ExodusIIReader(FileName="solution.e")
view = GetActiveView()
view.UseOffscreenRenderingForScreenshots = 0
Show()
Render()
WriteImage("test.png")
============== *snap* ==============

but merely got

============== *snip* ==============
Traceback (most recent call last):
  File "screenshot.py", line 12, in <module>
    view.UseOffscreenRenderingForScreenshots = 0
AttributeError: 'NoneType' object has no attribute
'UseOffscreenRenderingForScreenshots'
============== *snap* ==============

Something seems to go wrong with GetActiveView().
