Figure 14.7 Composite State with two States

Sections

UML: Cameo Simulation Toolkit 19SP3: GOTCHA: CreateObjectAction ignores an Artifact as 'classifier' even though Artifact is a Classifier

GOTCHA: UML/SysML: Cameo Simulation Toolkit 19SP3: A [true] or [false] guard on an ActivityEdge MUST be a LiteralBoolean, not just characters typed in, or the evaluation may give unexpected or ill-defined results

UML/SysML: Cameo Simulation Toolkit 19SP3: A parent Activity with a DecisionNode that uses a Activity as a decisionInput Behavior terminates immediately after the decisionInput terminates (but OpaqueBehavior works)

UML/SysML: Cameo Simulation Toolkit 19SP3: GOTCHA: Will not evaluate a guard using a token from a decisionInputFlow UNLESS a decisionInput Behaviour is explicitly defined (but Alf does)

Sample problems and example diagrams in graphical language specifications are NOT necessarily indications of how one should model on a real-world project! They often just serve to demonstrate a particular aspect of the specified language.

Not every task in Activity Diagrams is well-suited to graphical modelling; consider using Action Language Helper (ALH) or Action Language for Foundational UML (Alf)

Alf - the Action Language for Foundation UML - is a UML-friendly textual "surface language" intended for use together with fUML. Useful for those tasks in Activity and StateMachine diagrams that don't lend themselves to graphical modelling.
