UML24 — The containment between Activity and StructuredActivityNode has one end redefining and the other subsetting

Open Closed All
  • Key: UML24-35
  • Legacy Issue Number: 14994
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Steve Cook)
  • Summary:

    The containment between Activity and StructuredActivityNode has one end redefining (wrong) and the other subsetting (right). Because redefining and subsetting should be symmetric, this means that both ends are both redefining and subsetting. This is clearly wrong, because it would mean that all nodes and groups are StructuredActivityNodes. The

    {redefines activity, redefines inactivity}

    should be turned into subsetting.
