I have a Listen shape which has 2 branches each has a recive shape with active. After the Listen shape, i have a decide shape in that i am refering one of the receive shapes message’s property.
When i try to buld it i am getting “Use of unconstructed message Req1” in the decide shapes’ rule expression.
The only thing I can think of is that you are referencing the message Req1 in the branch of message Req2 (presuming that is the name of the other message). Can you double check to ensure that you have your message references correct?
