UML25 — Modeling sent messages in State Machines

Open Closed All
  • Key: UML25-675
  • Legacy Issue Number: 15145
  • Status: closed  
  • Source: Fundacion Tecnalia Research and Innovation ( Adrian Noguero)
  • Summary:

    Currently it is not possible to define formally in a state machine diagram that a behavior linked to a transition/state triggers a message to be sent through a port.
    I think that being able to formally describe this would in fact make this kind of diagrams very valuable for compositional verification of state machine diagrams. See "Towards the Compositional Verification of Real-Time UML Designs" by Holger Giese et al. for reference

  • Disposition: Resolved — UML 2.5
  • Disposition Summary:

    This issue is not entirely clear, but it would seem that the desired capability is available by using an InvocationAction
    with onPort, as now described more fully in the UML 2.5 beta specification in Subclause 16.3.3, under “Invocation
    Actions and Ports”.
    Disposition: Closed - No Change
