      Parameters:
      event - the event.

      Specified by:
      observe in interface Observer
      Parameters:
      event - the event.
      transientVars - transientVars passed from one Observer to another when processing a single Event. This may allow optimizations between observers.
      Throws:
      Exception - if an error occurs. All exceptions will be logged but not propagated, as the observation mechanism should never fail.
