[Paraview] Some tables cannot be located using paraview.simple python api

[Laurent Vanboquestal]

Hello,

I got this message "Could not locate array z in the input" executing code
coming from Python Trace using Paraview 3.8.1

Any Idea?

The weird things is that my sample code is working fine with some pvd file
(using vtu files), but not with some others ....
However, I can open the "non-working" one with paraview

The code executed is coming from the Python trace of Paraview 3.8.1
Is there a workaround for this kind of issues?

python test_view2.py
vtkPVDReader : [ ...........]
vtkPVArrayCalculator : [ ...........]
vtkPVArrayCalculator : [ ...........]
vtkThreshold : [ ...........]

Traceback (most recent call last):
 File "test_view2.py", line 297, in <module>
   my_representation7.ColorArrayName = 'z'
 File
"/usr/local/ParaView-3.8.1-Linux-x86_64/lib/paraview-3.8/site-packages/paraview/servermanager.py",
line 204, in __setattr__
   setter(self, value)
 File
"/usr/local/ParaView-3.8.1-Linux-x86_64/lib/paraview-3.8/site-packages/paraview/servermanager.py",
line 2364, in setProperty
   return self.SetPropertyWithName(propName, value)
 File
"/usr/local/ParaView-3.8.1-Linux-x86_64/lib/paraview-3.8/site-packages/paraview/servermanager.py",
line 253, in SetPropertyWithName
   prop.SetData(arg)
 File
"/usr/local/ParaView-3.8.1-Linux-x86_64/lib/paraview-3.8/site-packages/paraview/servermanager.py",
line 684, in SetData
   raise ValueError("Could not locate array %s in the input." % arr)
ValueError: Could not locate array z in the input.

Do you have any idea or workaround to avoid this?

Thanks a lot for your help,

Best Regards,

Laurent
