vtkAppendPolyData doesn't allow polydata's with only points (no cells) to be appended
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I wanted to change line 239 of vtkAppendPolyData.cxx from if ( numPts < 1 || numCells < 1 ) to if ( numPts == 0 )
to allow polydata's which only contain points to be appended to each other.
I checked in this change (1.105) to vtkAppendPolyData.cxx. The VTK tests passed, but some Paraview test failed:
514 - pvcs.RectilinearFractal (Failed) 584 - pvcrs.RectilinearFractal (Failed)
so I reverted my change.
These tests only fail if Paraview is built with PARAVIEW_USE_MPI ON.
Can someone take a look at why these tests are failing and recommit the new functionality?
