Summary0014693: vtkAssignAttribute needs input array to have a name
DescriptionvtkAssignAttribute needs input array to have a name.
E.g.
  vtkNew<vtkImageData> imageData;
  imageData->SetDimensions(2,2,2);
  vtkNew<vtkFloatArray> tensors;
  //tensors->SetName("tensors");
  tensors->SetNumberOfComponents(9);
  tensors->SetNumberOfTuples(2*2*2);
  for (int i = 0; i < 2*2*2;++i)
    {
    tensors->SetTuple9(i,1.,0.,0.,0.,1.,0.,0.,0.,1.);
    }
  imageData->GetPointData()->SetTensors(tensors.GetPointer());

  vtkNew<vtkTrivialProducer> tp;
  tp->SetOutput(imageData.GetPointer());

  vtkNew<vtkAssignAttribute> tensorsToScalars;
  tensorsToScalars->Assign(vtkDataSetAttributes::TENSORS,
                           vtkDataSetAttributes::SCALARS,
                           vtkAssignAttribute::POINT_DATA);
  tensorsToScalars->SetInputConnection(tp->GetOutputPort());
  tensorsToScalars->Update();
  vtkImageData* output = vtkImageData::SafeDownCast(tensorsToScalars->GetOutputDataObject(0));
  std::cout << "Scalars: " << output->GetPointData()->GetScalars() << std::endl;

It prints "Scalars: 0". However, if the tensors array has a name, then it prints the array address correctly.
