[Paraview] Insert text source into view in a script

[M. Nawijn]

Hello Utkarsh,

Thank you for the fast response. I tried this already before posting
my question to the mailing list, however, when I inserted the Show(),
I get the following error:

vtkFileSeriesReader : [ ...........]
vtkPainterPolyDataMapper : [ ...........]
vtkPainterPolyDataMapper : [ ...........]
Traceback (most recent call last):
  File "test3.py", line 39, in <module>
    Show()
  File "/home/nawijn/scratch/paraview-bin/Utilities/VTKPythonWrapping/paraview/simple.py",
line 112, in Show
    rep = GetDisplayProperties(proxy, view)
  File "/home/nawijn/scratch/paraview-bin/Utilities/VTKPythonWrapping/paraview/simple.py",
line 101, in GetDisplayProperties
    return GetRepresentation(proxy, view)
  File "/home/nawijn/scratch/paraview-bin/Utilities/VTKPythonWrapping/paraview/simple.py",
line 90, in GetRepresentation
    rep = servermanager.GetRepresentation(proxy, view)
  File "/home/nawijn/scratch/paraview-bin/Utilities/VTKPythonWrapping/paraview/servermanager.py",
line 1989, in GetRepresentation
    if rep.Input == aProxy:
  File "/home/nawijn/scratch/paraview-bin/Utilities/VTKPythonWrapping/paraview/servermanager.py",
line 357, in __getattr__
    return getattr(self.SMProxy, name)
AttributeError: Input


Any suggestions?
