Activity Diagram: Behavior

I have an activity diagram.
I want to associate “behavior” action to an action element.
Why there aren’t all activity diagrams options in the list of “behavior action”?

Please see the attached document for more details.

Thanks, Anna

Hi Anna,

You can only call an activity model for Behavior of an action. In UML Superstructure Specification v2.2 (we fully follow the specification):

  • page 244 mentioned that the behavior property of CallBehaviorAction is of type “Behavior”
  • page 236 mentioned that Action is of type named element but not behavior
  • figure 12.64 in page 349 shows calling an activity but not calling an action

In your project file, you only have one activity model “Save” which is on the activity diagram “Save”, so it’s the option in Behavior of the action model.

P.S. UML Superstructure Specification can be got from
