[Paraview] Paraview support of FieldData in a vtkTable

[livia.barazzetti at istb.unibe.ch]

Hello,
I am thinking to store some info as FieldData of a table (for example, the parameters used for the calculation of the data in the table - possibly they could also be changing depending on other elements of the pipeline). I tried a toy example in Python and it seems that vtkTable supports it (I am able to add an array and read it back). In Paraview 4.3.1, visualizing the field data from a python annotation works, but  if I open the spreadsheet view to see the field data I get
Warning: In C:\DBD\pvs-x64\paraview\src\paraview\ParaViewCore\VTKExtensions\Rendering\vtkMarkSelectedRows.cxx, line 209

vtkMarkSelectedRows (0000000010381890): FieldAssociation type not supported yet. Selected elements may not be shown correctly.


, also the writer doen't export the field data.
Should I go forward in using the FieldData of a table (just remembering that before exporting I should use a Python annotation or a programmable filter to read the field data) or it is actually not supported by paraview and I should avoid it? (for example, the field data would not be updated as the rest of the pipeline, or something like that)?
Thank you
Best regards
Livia Barazzetti
