Jeroen and Dan ran this tutorial at the J-Fall 2012 conference as a 50 minute-long session. It seemed to go well, though we reckon you probably need about 90 minutes to complete it.
The tutorial is based on a slightly-modified version of the quickstart archetype, configured to use the Wicket viewer and JDO ObjectStore and pointing at a snapshot in the Apache snapshot repo. You can download the zip here; the PDF for the tutorial is here.
And if you've built Isis locally, then you might want to tweak the pom.xml of the app to reference the latest-n-greatest snapshot.
