I'm trying to do something very similar. I've got two controllers, one for a div/tree and another for a div/list. I'd like to raise events from the tree controller that are handled by the list controller. I know I can wire them up if I bind/trigger the events based directly on the DOM elements, but I'd much rather bind/trigger the events on the controller objects themselves.
Does anyone know if this is possible? Am I thinking about the problem wrong?
