[Paraview] PV 3.12.0 coprocessing problem when using multiple filters

[Takuya OSHIMA]

Hi,

I am trying to explore the coprocessing capability of PV 3.12.0. When
I create a pipeline with a single slice filter within the PV GUI,
export the Python state file by the coprocessing plugin and run the
script as the coprocessing pipleline in my simulation code, it works
fine.

However if I create a pipeline with two or more filters my simulation
code issues an error from the coprocessing library (the error message
is for the case of two slice filters):

Traceback (most recent call last):
  File "<string>", line 2, in <module>
  File "/Users/ohshima/shindoriTest/twoSlices.py", line 323, in DoCoProcessing
    DataRepresentation2.ColorArrayName = 'p'
  File "/Volumes/RAID0data/paraview/3.12/build/Utilities/VTKPythonWrapping/site-packages/paraview/servermanager.py", line 212, in __setattr__
    setter(self, value)
  File "/Volumes/RAID0data/paraview/3.12/build/Utilities/VTKPythonWrapping/site-packages/paraview/servermanager.py", line 2276, in setProperty
    return self.SetPropertyWithName(propName, value)
  File "/Volumes/RAID0data/paraview/3.12/build/Utilities/VTKPythonWrapping/site-packages/paraview/servermanager.py", line 267, in SetPropertyWithName
    prop.SetData(arg)
  File "/Volumes/RAID0data/paraview/3.12/build/Utilities/VTKPythonWrapping/site-packages/paraview/servermanager.py", line 695, in SetData
    raise ValueError("Could not locate array %s in the input." % arr)
ValueError: Could not locate array p in the input.

The problem is same for Mac OS X 10.6 and RHEL 5.1 64bit. I attach the
scripts oneSlice.py (which works) and twoSlices.py (which does not
work). Can anybody shed light on the problem?
