Creating an accept event action
You can create an Accept Event Action through an Activity Diagram or a Modeler pane.
When you create an accept event action you must create or select an Event to use.
• If you select an Event of type Opaque that has 'In' or 'In and Out' Parameters, Modeler creates Output Pins on the Accept Event Action for those Parameters.
• If you select an Event of type Signal that has Attributes, Modeler creates Output Pins on the Accept Event Action for those Parameters (Unmarshall check box selected) or an Output Pin that is linked to the Signal (Unmarshall check box cleared).
• If you select an Event of type Call that is triggered by an Operation that has 'In' or 'In and Out' Parameters, Modeler Output Pins on the Accept Event Action for those Parameters.
