EventHandling.WaitForEvent(EventSourceTerm, EventVariable);Description
The OTX WaitForEvent activity blocks the current flow (thread) until a specified event sources has triggered an event. When an event is triggered, completed the WaitForEvent activity and the process continues with the next activity. The event that led to the termination of the activity can be evaluated using the Event property, see below.
Ending the waitforevent activity, all on-the-fly (ie on the corresponding event source term, see Property Source) event sources generated automatically.
