Problem with JMS Trigger

Situation:

The flow works if triggered manually, however when I use a JMS event it gives the following error:

com.adeptia.indigo.services.ServiceException: Time has been expired to receive message

Cause:

If the flow works when triggered manually and there is a message in the queue, then the event is picking up the message but not passing it to the JMS source activity

Solution:

Set the "event context enabled" property of the JMS source to "true" in the Process Designer
