[vtkusers] User Interaction with MultiBlocDataSet with unstructured Grid

I have a MultiBlockDataSet composed of severals unstructuredGrid (tetra,
hexa,...). All The cells share the same points array and I have some blocks
'cells of the data set that share the same points.
The idea is to move a point belonging to a cell of block 1 and to acell of block
2. Like this, because points array is share.
But, to render the multiblockdataset, I use a vtkCompositeDataGeometryFilter
that give me a vtkPolyData.
Then I use the http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/MoveAVertex
example to select and move points.
The problem is that the points have been duplicated and are now independant (no
more use of the global points array).
So, is there a way to preserve the points array information in order to well
move points and preserve the topology ?
