Livia,

It seems reasonable that you should be able to save field data stored in a vtkTable. Would you mind writing up a feature request at http://www.paraview.org/Bug/view_all_bug_page.php?

Thanks,
Cory

Hi,
I was using the writer from the gui  in Paraview. I created a very simple programmable source (with output type vtkTable) with a column and a field data array, then clicked File-Save Data from the menu.
In the case of a table, the writer window doesn’t allow to specify the association field, so only the row values are exported to the csv file.
By the way, I see that if I apply a TableToPoints filter, the field array is copied to the polydata correctly (and can be exported from there), but I haven’t experimented with this solution further yet
Thanks
Livia

Livia,

Which writer are you using that doesn't save the field data?

Thanks,
Cory

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
