Phew! After *hours* of debugging, the problem was (not in any of the
code I posted) that when I DeepCopy()-ed an array:

  vtkSmartPointer<vtkDoubleArray> weights =
      vtkSmartPointer<vtkDoubleArray>::New();
  weights->DeepCopy(originalWeights);

I didn't set the name of the array to match:

  weights->SetName("Weights");

I guess I assumed that would have happened in the DeepCopy()??

Oh well, lesson learned!

Thanks,

David
