[Paraview] small ParaView Script not working

[Marco Kokic]

I found the reason for print cells_ None, which is that I used the wrong 
datareader, instead the script should look like this:

#!/usr/bin/pvpython

#setup paraview connection
from paraview.simple import *

cells_ = 
XMLMultiBlockDataReader(FileName=['/home/me/Dokumente/TEST/Cells_0.vtm', 
'/home/me/Dokumente/TEST/Cells_100.vtm', 
'/home/me/Dokumente/TEST/Cells_200.vtm'])

# create a new 'Integrate Variables'
integrateVariables1 = IntegrateVariables(Input=cells_)
# set active source
SetActiveSource(integrateVariables1)
# create a new 'Plot Selection Over Time'
plotSelectionOverTime1 = PlotSelectionOverTime(Input=integrateVariables1)
# save data
SaveData('/home/me/Dokumente/TEST/TEST.csv', proxy=plotSelectionOverTime1)


Still the rest of the script doesn't work. I tried to trace every step 
when using the gui and saved it as a macro. Doesn't work.
