6. Behavioral Diagrams

Behavioral diagrams are used to show the functionality of the system and include Use Case, Sequence, Collaboration, State Machine, and Activity diagrams.

Poseidon limits the inclusion of certain elements to only one instance in one behavioral diagram. As a result of this policy, the context menu option 'Add to Diagram' may be greyed out when a behavioral diagram is active and the selected element has already been represented in one of these diagrams.
