A reminder that pre 3.5sdk there is a bug where the responder can get called
twice.
Bug SDK-22883 Incorrectly Functioning HTTPService responders are called twice
Steps to reproduce:
1. Run HTTPServiceTest.mxml from the attached zip file. It calls one service
that should succeed and one service that should fail.
Actual Results:
The result and the fault method of the AsyncToken responder are called twice.
Expected Results:
Each method should be called only once.
Workaround (if any):
Add a result and a fault listener to the HTTPService directly. Then the result
and the fault method of the AsyncToken responder are called only once as
expected.
