Two releases to the reference today. You can make these changes all at once if you like. I simply forgot the 2.0.3 fix when I did 2.0.2, so I just followed up immediately with 2.0.3.
This fixes all outstanding issues with the reference implementation. See the release notes page for the AS3 Standard Version: http://trac.puremvc.org/PureMVC_AS3/wiki/ReleaseNotes
Also note the changes in the unit tests: http://trac.puremvc.org/PureMVC_AS3_UnitTests
