E231 Availability of Events

Umple semantic error related to state machine operators

When an event name is used with a specific name for its state machine, the state machine and event must be available in the trait, otherwise, the Umple compiler raises this error.

Example

// In this example, there is an error because event e2() is not available in state machine sm.
trait T {
  sm{
    s0{
      e1-> s1;
      s11{ e12-> s12; }
      s12{ e11-> s11; }   
    }
    s1{ e0-> s1;  }  
  }
}
class C {
  isA T<sm.e2() as event2>;
}
