I'll be presenting on Tapestry 5 at JavaZone. I'll be in Lab 2, on Sept 18th, at 2:15. With less than an hour to talk about Tapestry 5 and compare it briefly to Wicket and Rails ... well, I'll be talking fast!
I also just noticed that there's a session on comparing IoC containers that includes Tapestry 5 IoC. That's Lab 6, on the 17th, at 5pm.
