Hi,
When using 'beforeunload' event you need to use synchronous Ajax call.
Additionally you need to prevent the default behavior of the JavaScript
event to stop the leaving of the page.
Instead of doing your manual work in
AbstractDefaultAjaxBehavior#renderHead() you can just use
AjaxEventBehavior("beforeunload")
