When the first Event in the Event Gateway configuration is triggered, then the path that follows that Event will used (a token will be sent down the Event’s outgoing Sequence Flows). All the remaining paths of the Event Gateway configuration will no longer be valid. Basically, the Event Gateway configuration is a race condition where the first Event that is triggered wins.

The event-based gateway has the following additional properties:
