Hi Martin, I couldn't make it work in the Playground... Maybe my code is too long because it always throws this error - 052715 playground.Application[f]: TypeError: this.getTarget().getRoot() is null...
Anyway, I've attached a demo file http://n2.nabble.com/file/n4105146/Application.js Application.js to this post. The /** ISSUE HERE **/ comment shows where the problem seems to be. Best, Benoît.
