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 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 in the Activity Editor

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.

Diagram Toolbar

The activity diagram toolbar assist you during modeling an activity diagram:

The available tools are:

Tool Icon	Tool Name	Description
	Select in service panel	Select the related operation in the service panel.
	Reload diagram	Click on this icon to reload the activity diagram.

Elements Toolbar

The elements toolbar contains all elements that you can create on your activity diagram.

Icon	Description
	Add a final node. An activity diagram can have multiple final nodes.
	Add an object node. This can be used to store data locally.
	Add a decision. Decisions are used to split the control flow based on conditions/guards.
	Throw the exception defined by the parameters. If this error is not caught, it will be sent back to the client. For more information, refer to User Defined Errors in the xUML Services Reference Guide.
	Add a literal. It can be connected to output parameters, return parameters or pins (action call or throw exception) that do not have incoming relations.
	Add a comment. This has no effect on the execution, it is just for documenting purposes.
	Add a mapping operation.
	Add an action script operation.
Image Added	Add a JavaScript operation.
	Add an activity operation.

Activity Diagram Context Menus

You are supported during modeling on the activity diagram pane by various context menus:

• Tools Context Menu
• Extended Tools Context Menu
• Control Flow Context Menu
• Diagram Context Menu

Tools Context Menu Anchor tools_context_menu tools_context_menu
	If you right click on an element, the tools context menu opens. Use it to edit the current element. The following options are available (the options depend on the selected element): Icon Description Delete the element. Bring the element to the front. Send the element to the background. Align the element to the grid. Open the implementation of the element in a new tab. Jump to the element in the Service panel.
Extended Tools Context Menu Anchor x_tools_context_menu x_tools_context_menu
	If you have selected more than one element on the pane, the tools context menu is enhanced with additional options. The available options depend on your selection on the diagram pane: Icon Description Align left Align right Align center Align top Align bottom Align middle Distribute horizontally Distribute vertically Align relation Tip If you want to align a relation between two elements, mark the pin(s) to apply the corresponding alignment functionality.
Control Flow Context Menu Anchor relation_context_menu relation_context_menu
	Right-click a control flow to open the context menu. The following options are applicable to control flows: Icon Description Delete the relation. Bring the relation to the front. Send the relation to the background. Align the relation.
Diagram Context Menu Anchor diagram_context_menu diagram_context_menu
	With a right-click on the diagram pane itself, you open the diagram context menu: Icon Description Jump to the related operation in the Service panel.
