Adding Action Nodes to the Diagram Pane
| Tip |
|---|
You can do this with any operation: Operations from your data model or the Base Types, as well as operations from imported libraries or connectors. |
Dropping an operation on the activity diagram creates a call operation action and the related pins.
| If you want to create a new operation, you can click the corresponding operation icon in the elements toolbar and drag it to the diagram pane. You can create the following types of operations directly from the toolbar:
The example on the left shows how to create an action script operation.
| ||
| The new operation is now displayed in the activity diagram and you can enter its name directly into the element.
| ||
| You can create parameters directly in the Activity Editor using the two icons above the operation. They appear when you hover over it with the mouse. You can also create parameters via the service panel. |
| Info |

If you
the activity diagram is not updated automatically. You will get a warning message in the validation panel that you need to reload the activity diagram to see all pins of the relevant operation. You can click this warning message to highlight the relevant operation in the diagram. |
| The newly created operation is also displayed in the Implementation folder of the service panel. It resides within the same class as the activity operation to which it was added. | ||||||
| Once added to the diagram, you can move action nodes any time. Click the action node and drag it to a new position. | ||||||
|
| ||||||
| You can hover over the action node to see a tooltip showing the full operation name and path. | ||||||
| Hovering over an operation pin shows the direction, the name and the full path of the type. |
