Description

In all the message exchanges where the response is send this issue comes which can be explained by following scenarios.

Scenario 1: Synchronous messages exchange via wsdl call.
When process is invoked and reply is send in "response" activity after that one forEach loop is their.Process is invoked by INVOKE_INTERNAL job and with the same job with REPLY, response is set and moves to forEach without sending the response, which is expected as response will be send after the transaction is committed (following code illustrates).

_engine._contexts.scheduler.registerSynchronizer(new Scheduler.Synchronizer() {
public void afterCompletion(boolean success) {
__log.debug("Received myrole mex response callback");
if( success )

{ ResponseCallback callback = _waitingCallbacks.remove(cid); if (callback != null) callback.responseReceived(); }

else

{ __log.warn("Transaction is rolled back on sending back the response."); }

}
public void beforeCompletion() {
}
});

So, the response is send after the forEach (there can be other scenarios as well other than forEach) which delays the response.

Scenario 2: Synchronous messages exchange via template call.
Instead of invoking process with wsdl call (as done in scenario 1) we do by template call (receive-reply two-way invocation) then also same issue comes as described in scenario 1.

Scenario 3: Asynchronously sending response via template approach.
Response is send by INVOKE_INTERNAL job and that job is not committed until forEach is executed.
