[xwiki-users] Re-register / Un-register / List EventListeners

Hello all, I've followed the tutorial at http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingEventListenerTutor… and gotten it to work, but now I can't change the code in the event listener to do anything different, how do I force my event listener to re-register and take changes in the onEvent ComponentMethodClass? Also, is there a way to list listeners currently in effect, I suspect that there are instances of my previous attempts still "listening" since it doesn't seem like I can use the same "Role Hint" twice. At least when I deleted my previously working attempt, then made the same solution again using the same "Role Hint" again the code wouldn't run, then I changed the "Role Hint" value and it ran. Leading me to believe there are orphaned listeners out there.
