Well, for one this simply didn't work without it, I'm guessing because of javascript's async nature and perhaps because I'm calling an event within an event.

Adding a 500 millisecond delay made it work - that's really the thing I'm unhappy about. When you find yourself using `setTimeout` to get things to happen at the right time, you're probably not using the evented framework properly.  I couldn't see another event or another way in plugin context to do this though, maybe the main paella folks will have a better idea.
