Rational Rhapsody 8.0
Rational Rhapsody 8.0.6

APAR status

• Closed as program error.

Error description

• Transition from join to terminatin connector results in one of
  the concurrent state's 'Action on Exit' not being called

  * RECOMMENDATION:                                              *
  ****************************************************************
  In cases where orthogonal states exit to a join connector
  that is followed by a termination connector, the code that
  is generated always uses the exit action of the first state
  regardless of which of the orthogonal states the system was
  in.
  

Problem conclusion

• Fixed in version 8.0. To preserve the previous code
  generation behavior for pre-8.0 models, a property called
  CG::Statechart::UsePre80StatechartCG was added to the
  backward compatibility settings for C, C++, and Java with a
  value of True.
  
  In the original description of the item, the user also
  indicated that there is an additional defect: the exit
  action of the AND state containing all orthogonal components
  is not executed. Since the target of the compound
  transitions is a termination connector (terminate pseudo
  state), this is not a defect according to the UML
  specification. Following is a citation: "Entering a
  terminate pseudostate implies that the execution of this
  state machine by means of its context object is terminated.
  The state machine does not exit any states nor does it
  perform any exit actions other than those associated with
  the transition leading to the terminate pseudostate."
