vtkXMLPMultiBlockDataWriter does not support vtkPartitionedDataSet
I read in a .cgns file, did an extract subset with seed filter. I tried to write out the resulting dataset as .vtm (vtkMultiblock) data. I got the error:
ERROR: In /home/buildslave/dashboards/buildbot/paraview-pvbinsdash-linux-shared-release_superbuild/build/superbuild/paraview/src/VTK/IO/ParallelXML/vtkXMLPMultiBlockDataWriter.cxx, line 175 vtkXMLPMultiBlockDataWriter (0xa32d160): Unsupported composite dataset type: vtkPartitionedDataSet
and
