If you want to keep changes to a minimum, you *can* change the attribute of 'async' on a node in a currently deployed definition in the database to true. So...

Extending the job is the first time I've heard of this. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4237961#...
