Adding a tasklistener to a deployed process

[davidwaf]

Dear all,
Is there a way to programmatically add a TaskListener to an already deployed process ?
I have a process already deployed, i realize i had forgotten to attach listen to it.
Thanks.

Hi,

The issue is that you already have running instances right?
If you deploy a new version of the process definition with the task listener then all new process instances will be started with that definition.
For already running process instances I think it's not possible to add it.

Best regards,

There is an undocumented api call that migrates a running process to a new version, but this is ONLY safe if few things change. Just adding a tasklistener would be one of the safe changes.

And …  what is that API call? Please, advise.

Alright, i get. I just re-deployed and started over with the listeners in this time.
