How to listen to process instance activity ?

wir33658 — Wed, 16 Jun 2010 19:51:32 GMT

Hi, is there any possibility to add a listener to a process instance, so I can act on what ever is going on. (Somehow I need to hook in to do some automated stuff).Cheers, Rob.

Hi Rob,

Adding listeners to process execution events is something that is a must for Tom, so I'm sure it will be implemented in the next months.
The problem is there is no BPMN 2.0 compliant thing to do this, so we are currently still investigating what would be the best approach to do this.

Hi, hm, you mention BPMN, but I am thinking of adding listeners to the process machine/engine to get every state changed on a process instance (not events which I would need to set up in the model, e.g. BPMN).

Cheers, Rob.

that will come as a process event bus. first ideas should hopefully make it in the next release.

Sounds great, thanks for the update on this one.

Old subject, but I checked the recent state of the project and cannot point out such a event-bus. I hope that there is something like this meanwhile and someone can point it out to me (a little example would be very helpful).

(Something like "processInstance.addListener(…)" 😉 ? )

Cheers, Rob.

the process event bus never made it into the code.
You can however define process instance listeners to your process: http://activiti.org/userguide/index.html#executionListeners.
If you want a global listener for all process instances, you need to use a ParseListener and hook it into the BpmnParser.

How do I get access to the BpmnParser ? I checked the API (http://activiti.org/javadocs/index.html) but could not figure out how to get the parser instance and then hook in via a listener. Is there any example ?

But anyhow, I am not sure If this is what I am looking for.

In general, I need to get informed on each step/node the engine is doing/passing on a specific process. This way I am able to follow exactly what is going on and update e.g. the bpmn-graph in a GUI or … .
