The tutorial uses some constructs which have been deprecated in QooXdoo 3.0 - ie the "manifest": "https://github.com/ergobyte/qookery/releases/download/0.1/qookery.json" line and use of qookery.contexts.Qookery.loadResource produces warnings.
In the end, the tutorial doesn't seem to work properly.
Thank you for your comment, we will take care of the tutorial update. What kind of warning do you get from loadResource? If it is about the synchronous XHR?
