Fetch parent instance id using subprocess instance

[steff1]

Hi there

I would like to get the id of the parent process instance. Is it always sufficient to make the following calls based on the ProcessInstance of the subprocess?

subProcessProcessInstance.getSuperExecution().getProcessInstanceId()‍

I'm just wondering if there is any case where this is not sufficient.

Thanks in advance
Stefan

In case you have more nested subprocesses, you have to be careful. Otherwise it alwyas gives you the id of the execution from which the sub process instance was spawned.

Thanks for the reply!

Which cases do you mean could fail?

I already tried a two level sub process hierarchy (parent calls subProcess, subProcess calls subSubProcess). There I'm able to went up the hierarchy with the mentioned expression.

Cheers,
Stefan

I'm thinking a more complex combination with multi instances, concurrencies and everything else that might go wrong 😉
