[Paraview] A little help with understanding how the pipeline works please

[no name]

The Update.Pipeline() thing worked perfectly as you suggested. But now
I get an error I cant' read any information form:

RROR: In C:\bbd\b51c3c7f\source-paraview\ParaViewCore\ServerManager\Core\vtkSMEnumerationDomain.cxx,
line 75

vtkSMFieldDataDomain (00000000610CD930): Invalid idx: 0

But everything seems to look fine ... But I feel very uncomfortable
about ignoring it :( The information I read in comes from multiple INP
files.

Thanks
Richard
