Nature: Revision
Severity: Significant
Summary: Category: Major




In the StateMachine section “Event processing for state machines”, there is an explicit statement: “for passive classes it can be implemented using a monitor”, which suggests that passive classes implement the run-to-completion paradigm. This implies that passive classes can have classifier behaviors. Perhaps this capability should be removed, but, it may not be backward compatible and might invalidate numerous existing designs (e.g., Rhapsody models).

Issue: Can passive classes have ClassifierBehaviors?

Category: Major


In the StateMachine section .Event processing for state machines., there is an explicit statement: .for passive classes it can be implemented using a monitor., which suggests that passive classes implement the run-to-completion paradigm. This implies that passive classes can have classifier behaviors. Perhaps this capability should be removed, but, it may not be backward compatible and might invalidate numerous existing designs (e.g., Rhapsody models).
