[vtkusers] vtkGeometryFilter question

[Flanery Jr, Raymond E.]

I am using vtkGeometryFilter in a similar fashion to the test example eleState.tcl in a python code. The problem I am running into is that at the end I need to be able to get access to the original cellId and tkGeometryFilter is giving every actor a new cellid. How can I retain the original cellId so that I can use vtkCellPicker to return that value for me?
