Issue querying for Signal

[jpgouin]

Hi,

I have a problem regarding the query of signal.

I'm trying to use signalEventReceived(signalName,executionId) to trigger a boundary signal. However it does not work, it says that Execution xx has not subscribed to a signal event with name xx.

And when I query for the active execution , there is no eventSubscription, the list is empty.

But when I inspect the execution (in Java , in debug mode)   I can access the executions object which contains the ScopeExecution and this scope contains the SignalEventSubscriptionEntity of the correct signal.

Is it possible to access the ScopeExecution  through the runtimeService , if so how can I get the proper ScopeExecution  id and which query shall I use?

Maybe there is something wrong with my bpmn , because the request

runtimeService.createExecutionQuery().signalEventSubscriptionName(signalName) should be returning the execution that has the signal register but it return null instead.

I'm using Activiti 5.19.0.2 integrated into ServiceMix and Camel.

Thanks for the help,

Jean-Philippe.

Hi,

I had a detailed look at your post today.
I don't think timer, event and signal boundary events work on script/services/camel tasks in Activiti...not sure if it is by design or a defect! Feel free to raise an issue or even a contribution (which would be great!) assuming it is valid as per BPMN 2.0 spec. This is probably the main reason why you not able to trigger a signal attached to your Camel task.

Regarding the async setting I mentioned, assume that Activiti supported boundary signals/messages on Camel task, then I would expect those message/signal subscription to work only after the activity it is attached to is persisted to database (which is essentially controlled by the setting of async flag explained at https://activiti.github.io/userguide/5.19.0/index.html#asyncContinuations).

Is your camel task a very long running task? If that is the only reason for a boundary event, you can achieve that using a Camel + Receive Task pattern as explained in the user guide https://activiti.github.io/userguide/5.19.0/index.html#bpmnCamelTask.

A normal Camel + Receive Task pattern that is used in the following test cases in Activiti are working fine
https://github.com/Activiti/Activiti/blob/5.x/modules/activiti-camel/src/test/java/org/activiti/came... 
https://github.com/Activiti/Activiti/blob/5.x/modules/activiti-camel/src/test/java/org/activiti/came... 
With the above pattern, I was hoping that I can include a boundary signal on the receive task if I want to terminate it using external signals...However there appears an issue when there are boundary events on those receive tasks. Looks like the Camel Behavior in Activiti is not completing the boundary events when Receive Tasks are completed...

Feel free to raise an issue on this in Activiti. Btw, until this issue is fixed, you might be able to achieve similar external signaling + camel signaling functionality by altering the process model a bit. Please find attached the project I used to test these behaviors. Hope this helps!
