As BPEL specification is saying, missingReply is thrown when an inbound message activity has been executed, and the process instance or scope instance reaches the end of its execution without a corresponding <reply> activity having been executed.
But when I have process:
receive
assign
– there should be a reply which is missing
I won't receive anything, SoapUI will timeout and on the server side, It's doing nothing If It reach end of process and then will throw java.util.concurrent.TimeoutException, because It's waiting for response.
