When you open the implementation of an operation that has been implemented as activity, the activity diagram opens in the activity editor.

Customizing the Activity Diagram Editor

The diagram pane shows the torso of an activity diagram: only initial node and final node are present. This leads to the validation panel showing errors because a control flow is missing.
Refer to the other pages in this chapter for more information on how to draw a valid Activity diagram:

Modeling on the Diagram Pane

While modeling, some general functionalities help you to browse through your model, and to adjust your working location within the model. Refer to Customizing Editors and Panels for more details.

Toolbars

The activity diagram editor features a diagram toolbar in the center top of the diagram pane, and an elements toolbar on the right.
