Adding an operation to a transition
An operation is an external prompt, represented by an interface, that attempts to trigger a movement from one state to another.
To add an operation to an existing transition, proceed as follows:
Procedure
- On the canvas, select and hover over the transition that you want to modify.
- In the action bar that appears, click the operation icon
as shown in this image.
- In the Properties area, configure the settings in the Description tab to point to the required interface and operation.
Results
Your newly created operation will appear on the canvas on top of the transition that it is associated with.There are some rare instances in the runtime environment when an operation can exist and not be associated with a transition. If this operation is triggered during processing, then one of two things can occur. If a fault is defined on the operation, it is returned; otherwise, the business state machine does nothing, and sits in the current state and waits for a valid operation.
