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.
