FlexSDK IResponderbug

When working withproxies in puremvc i decided to separate the remotecalls into a delegate class. Im calling this class from the proxy and passing in a reference to the proxy. The proxy class implements the IResponder interface so result and the fault handler is in the proxy class.
Using Log4Fx plugin from farata systems i discovered that the result handler being called twice for every result.
Naturally i assumed the error was in the pureMVC framework so i posted it in one of the pureMVC forums
Cliff was kind enough to point me to this entry, where it shows that this is a bug in the SDK and not in the pureMVC framework.
