[vtkusers] question about vtkCommand

[qlizhi]

hi, all!
i write a subclass of vtkCommand, and in its function Execute(), i try to change an actor's Orientation by code [actor->SetOrientation(ori)].
I made breakPoint on that line, it runs. But   the renderWindow  show nothing. Can anybody tell me why?
Sorry for my poor english!
