Retrieving all message and signal subscriptions for a given executionId

[pclaeys]

Hi,
Background:
Building an inspector tool that visualizes the exection tree; so an administrator can know : 'what is a given process waiting on at the moment ? '  -> it's useful to see what on which messages or signals an execution is subscribed .

Question:
How can we retrieve on which BPMN messages and BPMN signals an execution is subscribed, using the activiti java api?

We can retrieve timers for a given execution by using

 managementService.createJobQuery().executionId(String executionId) ‍

Is there a similar feature for retrieving subscriptions - other than fetching by sql ?

Hi pclaeys, nice seeing you here 🙂

Signals and messages are stored as 'event subscriptions'. There is a 'hidden' API in the EventSubscriptionQueryImpl() which you can use to query event subscriptions like that using the execution.

Hi Joram,
