[Paraview] Thresholding a RectilinearGrid

[Stephens, Michael M ERDC-ITL-MS]

folks,

hopefully i missed something that's already out there; but this has me
scraatching my head.

what i'm doing is simple enough.
took a Rectilinear Grid (aaa.vtr) and did a  Threshold using one of the cell
arrays.

then since i'm gonna use this later i save it out as a vtu.

when i try to read this file back into pv i get the following error:

ERROR: In
/viz/home/stephens/Kitware/ParaView/ParaView_cvs_350/ParaView3/VTK/IO/vtkXMLU
nstructuredDataReader.cxx, line 653
vtkXMLUnstructuredGridReader (0x1a0dd20): Cannot read cell connectivity from
Cells in piece 0 because the "connectivity" array is not long enough.

Cells in piece 0 because the "connectivity" array is not long enough.


using a pv checked out a few weeks ago.

i replicated the process (read, threshold, write) in a vtkpython script using
vtk checked out yesterday (v5.5), te outpt vtu file still has the same
problem.


any one ever see this before?
