This is the source code to the ActionScript layer of my extensive tutorial on BlazeDS and RobotLegs. It starts at http://tobiasgoeschel.com/2012/blaze1/, which handles creating a BlazeDS project via Maven. The part relevant to the source code here begins at http://tobiasgoeschel.com/2012/blaze3/, but you'll only get the whole picture if you've completed parts 1 and 2.
If you're interested, check it out!
