adding the progress observer with:
  dicom_reader->AddObserver(vtkCommand::ProgressEvent,progressBar);
 
the following callback is called while updating:
  void  Execute (vtkObject* aCaller, unsigned long aEID, void* aCallData)
  {
    vtkProcessObject* source = vtkProcessObject::SafeDownCast(aCaller);
  }
 
BUT
the SafeDownCast call returns 0. Why?
Any idea?

ps: this code was working with vtk4.4
