I have working code which uses a vtkCompositeDataGeometryFilter, but
simply a vtkPolyDataMapper, like this:

  VTK_CREATE(vtkCompositeDataGeometryFilter, geom1);
  geom1->SetInputConnection(0, eb1->GetOutputPort(0));
  geom1->Update();

  VTK_CREATE(vtkPolyDataMapper, mapper1);
  mapper1->SetInputConnection(geom1->GetOutputPort(0));

  VTK_CREATE(vtkActor, actor1);
  actor1->SetMapper(mapper1);
