ResultEvent that is passed to result handler in IResponder added to AsyncToken does not contain result

Steps to reproduce:
1. Call a webserive that returns a value
2. Take resulting AsyncToken
3. Add some implementation of IResponder
4. In implementation of IResponder trace the data param that is passed to result(data:Object) function.

Actual Results:
Param data is ResultEvent instance, however it does not contain result field with result from RPC.

Expected Results:

According to documentation on ResultEvent.result:
"Result that the RPC call returns. "

Param data should contain result field with result.

AsyncToken to which the IResponder is added contains this result.

Workaround (if any):
IResponder must contain the AsyncToken that is attached to, and in result method of responder one can use AyncToken result field to receive result from RPC.
