The workshop "Designing The Boundary - Rich UI Meets Efficient Java EE Backend" in Zurich will definetely take place. There are already 31 registrations - I forgot the size of the room - but in worst-case we will repeat at the next day (as last year - here the 2007 class feedback). I plan to discuss some controversial stuff from this blog and introduce some content of my new book (o'reilly), on which I'm working now. Beyond that - I will try to show your as much source code / working examples as possible. I will try to answer your questions in real time - with source code. I will code and deploy the apps in worst case :-).
So... see you in Zurich again!
