  // Updates the property using value obtained from the server. It creates
  // an instance of the server helper class vtkPVServerArraySelection
  // and passes the objectId (which the helper class gets as a pointer)
  // and populates the property using the values returned.
  // Each array is represented by two components:
  // name, state (on/off)
