Hi,I have got a question on the following scenario:Lets say that I have a BPM process that has 2 steps:'Human Task' followed by a 'Intermediate Catch Message Event'.The below code works perfectly fine if I notify the instance that is already sitting in a 'Intermediate Catch Message Event'.xxxxxxxxxx

runtimeService.createExecutionQuery().processInstanceId(processInstanceId) will return ExecutionQuery. You have to do .singleResult().get() on it to retrieve execution.

Hi Sam,

It is expected behaviour.
Queueing -> You can implement it by your own.

In the case when you fire an event to the relevant execution which is not listening on this event, nothing happens.

I'm facing a problem with message events.
After start the main process, while waiting for Task1 to complete, a message was received and subprocess started. When subprocess ends, a message is thrown to start subprocess event (SubEvent1). After SubEvent2 is completed a message is thrown and the Task4 has to catch the event and ends the main process.

Is that possible with Activiti 5.17.0???

Hi Mario,

I would say that your question is not related to the thread topic.
The answer is yes.

Thanks Martin.
Is there any plan to add this QUEUING mechanism into the notification service anytime soon. I am from the Oracle BPM background and it has a in-built QUEUEING mechanism where the Event stays in the Queue until the execution arrives at the Notification Wait step and then it notifies it automatically.

Hi Sam,

I do not have such a plan.
If you have such a need, you can implement it by yourselves and create pull request. Anybody from the team will provide you support.

Martin
