The reason why you can't grab the controller as a target of the MvcEvent prior to EventManager dispatch event (so even attaching to it at higher than 0 priority) is because this event itself is what makes the Application aware of what controller is going to be used.
The SharedEventManager listeners can be used instead, like it's done in EdpModuleLayouts. The difference is that the main EventManager is triggered by Application::run(). That makes the DispatchListener come into place and have it invoke AbstractController::dispatch(). This is when the controller is set as the event target, and then the SharedEventManager listeners are triggered, so those listeners have awareness of what controller is going to return the dispatch result even prior to its 'onDispatch()' method call. Also, your talking about a "main controller" that forwards to others. Now, you may have your reasons to do that, but that's generally not recommended. Controllers should not be altering the MVC flow, their task is just to deliver a result. Choosing what controller will be called is a concern of the Router; the Renderer will deal with the result if needed, i.e. when the result is a Response the cycle is short circuited by Application::run() instead. So if I got what you're trying to achieve, you should listen to post-route to deal with your 'forwarding', and then listen to [pre-render | post-dispatch | shared pre-dispatch] to deal with your layout selection. Since the way you deal with pre or post MVC events is actually priority, that makes any additional event unnecessary. You just have to get the provided ones right ;) Hope to be helpful.
