Event Driven Activity represents a sequence of Activities headed by a Receive Port Activity, Receive Send Port Response Activity, or Delay activity, i.e. An Activity that triggers some sort of event. When that event is realized the following Activities in the sequence are executed. Event Driven Activities can be within the scope of Event Handling Scope Activates or Listen Activities (which can contain multiple Event Driven sequences). This example workflow shows a typical use for an Event Driven Activity Sequence within an Event Handling Scope Activity. For more information see Workflow Basics – Event Handling.
