[Paraview-developers] Cannot load field data into block table

[Shawn Waldon]

Josh,

I ran across a similar issue last week.  The fix was to patch the VTK that
ParaView builds against.  I've attached the patch that addresses the issue
with multi block data and field data, it is the second commit in this VTK
branch:

http://review.source.kitware.com/#/t/4899

Let me know if this solves your problem,

Shawn
