Interactions and Activities

The behavioral aspects of Interactions and Activities are modeled using the 'Behavior' tab of the Properties window for the element, on which you assign parameters and return types to the elements.

Access

Select an Interaction or Activity element on a diagram or in the Browser window, then display the 'Behavior' tab of the Properties window, using any of the methods outlined here.

On the 'Behavior' tab, click on the button of the 'Parameters' field to edit the element's parameters on the 'Parameters tab'. When you create a new parameter using the 'Parameters' tab, it internally creates an Activity Parameter Node for an Activity or an Interaction Parameter for an Interaction.

In the 'Return' field, click on the drop-down arrow and select the return type of the element. Alternatively, click on the button and use the 'Select Type' dialog to locate the appropriate classifier.

The 'Specification' field is populated automatically when an operation is associated with the Activity or Interaction as a behavior.
