Jean, By looking at vtkDataSet::GenerateGhostArray() implementation it appears that ghost cell array will not be created if: - the grid extent is not 3D (I supposed it is not your case here) - if the the provided extents are the same than the data extents.
You might want to check if this last assertion is not valid for your case.
