I've been testing out what happens in the browser if the server goes down whilst handling a Direct function call. I'm using 3.3.1 and in ext-all-debug.js on line 26274 in the createEvent function, there is a reference to response.data which throws an error because response is null. Is there an intended way to hook events for what happens if the server goes down? At the moment I don't know how to handle this error.
