You're right, there were changes to the <send> impl. Two things happened here:

a) There was an older bug in Commons SCXML dealing with unnamed
events, which has been fixed via r389631 [1].

b) That will kill the "endless loop", but that still won't yield the
behavior you desire. For the EventDispatcher to come into play, you
must specify a targettype that is neither empty/unspecified nor the
String "scxml" (regardless of case). The SCXML WD assigns very
specific semantics to the targettype "scxml" (and an empty value
defaults to that). You will need to add a targettype to the <send>
element, see this version [2] of your test case along with the
testWizard02Sample() test case in this file [3] for all the details.

Thanks a lot for the test cases.. Let me know how things go :-)
