Customize Work Item Behavior to Subscribe a Contributor to a WI?
One answer
Daniel, that is not possible with JavaScript but you can code up a participant to do that. See http://rsjazz.wordpress.com/2012/08/02/subscribing-to-a-work-item-using-the-java-api/ about the API for subscription in general. Be aware that this is client API and you might have to use it slightly different in the participant. A good starting point for a participant would be http://rsjazz.wordpress.com/2012/11/30/a-create-approval-work-item-save-participant/ .
