Querying Message Intermediate Catching Event

Hi,
I've written an util method that get a DelegateExecution instance like JavaDelegate.execute(). I know there is a intermediateCatchEvent that waits for a message but I don't have the info about message name. I know also that the execution is waiting at that activity(I mean intermediateCatchEvent). How can I find the message name which intermediateCatchEvent is waiting for?
At that point when I called:

runtimeService.createExecutionQuery().processInstanceId(processInstance.getProcessInstanceId()).list()‍

or

((ExecutionEntity)runtimeService.createExecutionQuery().processInstanceId(processInstance.getProcessInstanceId()).singleResult())‍

I get 1 process instance, it doesn't give me any info about message subscription. I've tried

executionEntity.getEngineServices().getManagementService().createJobQuery().list()‍

but it gives nothing, I think it is only applicable to timer event, is that correct?

Thanks…

The job-query is only for timer-events, indeed. Messages are stored in the event-subscription-table. In our implementation, these can be queried when inside activiti-context, but it's not part of the public API:

<br>List<EventSubscriptionEntity> eventSubscriptions = commandContext.getEventSubscriptionEntityManager()<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .findEventSubscriptionsByNameAndExecution(MessageEventHandler.EVENT_HANDLER_TYPE, messageName, executionId);<br>
You can also use the BPMNModel (as of 5.12) or ReadonlyProcessDefinition (prior to 5.12) to get the activity-representation and inspect that to see what message-event definitions it has.
