Unstructured grid XML file without cells won't load
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I have a PolyData file that contains only points and a dozen associated scalars per point. I load this file in PV and use a Clip filter to extract a box-shaped region. If I then use Save Data to save the clipped output to a .vtu file the resulting file can not be read by PV. The error is
ERROR: In /home/kitware/ParaView3/Utilities/BuildScripts/ParaView-3.6/ParaView3/VTK/IO/vtkXMLUnstructuredGridReader.cxx, line 297 vtkXMLUnstructuredGridReader (0x8f59968): Cannot read cell types from Cells in piece 0 because the "types" array could not be found.
I guess this is caused by the original set having 0 cells, and subsequently the clipped output as well.
