[Paraview-developers] Weird quirk in the Exodus reader in Python

[Utkarsh Ayachit]

Alan,

Can you share a dataset to reproduce this, it'll be easier to figure
the issue out that way. If I was to make a guess, I suspect that the
reader reads array info etc. from the first file, if the first file
doesn't have all the info, it may not have things determined as
expected -- but that's just a guess.
