Query Signals/EventSubscriptions from api

jlew

Is it possible to query the event subscriptions for an execution using one of the the apis. I know the executionQuery of the runtime service allows us to filter executions that are waiting for a named signal provided you know the signal you want to filter. How would you go about getting a list of signals a processInstance (or execution) is waiting on or get the signal name it is looking for?

I am trying to generate a reporting/debugging script that allows us to inspect a running workflow and I would like to use the Activiti apis instead of going directly to the database.

Thanks

No, there is nothing (publicly) exposed. I believe there is an inner class though (EventSubscriptionQueryImpl) that might be used to base your use case on.

Not as clean as I would like but thank you, this gets what I need.

For those looking for something similar to this:

<br>String instanceId = "10335";<br>ProcessEngineConfiguration config = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();<br>ProcessEngine processEngine = config.buildProcessEngine();<br><br>List<EventSubscriptionEntity> o = new EventSubscriptionQueryImpl(((RuntimeServiceImpl)processEngine.getRuntimeService()).getCommandExecutor()).processInstanceId(instanceId).list();<br>
