In my JBPM system, I have implemented the ability to re-route tokens to where ever you want. I also got errors when trying to route if back to a start state. So as a solution, I have put in some validation which doesn't allow you to route it to the start state. Instead, it tells you to rather create a new flow. That's basically what you would be doing anyway. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130014#...
