No data while using "Object" as "resultFormat" for Sharepoint WebService

Steps to reproduce:
1. Import & Execute attached application.
2. Have a breakpoint inside "onSPResult" function and inspect the data

Actual Results:
result.Lists.List is shown as ArrayCollection. But, there is no data inside it.

Expected Results:
All the objects in the result should decoded properly.

Workaround (if any):
Use "e4x" or "xml" as the "resultFormat"
