UML14 — UML 1.4: Wrong target for StateMachine.top association

  • Key: UML14-84
  • Legacy Issue Number: 4739
  • Status: closed  
  • Source: Anonymous
  • Summary:

    A StateMachine compositely contains a State through the "top" association
    [UML 1.4, pp. 2-147, fig. 2-24].

    However, the wellformedness rules for StateMachine state that "A top state
    is always a composite: self.top.oclIsTypeOf(CompositeState)" [UML 1.4, pp.
    2-158].

    If that is the case, the top association should target a CompositeState, not
    the more general State.

    Note: of course this is not an error as such, but if a wellformedness rule
    can be expressed just as easily in UML, there is no reason to complicate
    matters
