Description
I used the FB4 "Connect to web service" option to generate wrappers for a simple web service. The soap response is sent and received and misinterpreted by the XMLDecoder class. I'm not sure if I've got the correct Component (or even Project), but it looks to me like an SDK problem.
I'm including the wsdl and the soap send and response for a simple webservice that adds two numbers. Hopefully this makes the problem reproducible. The issue appears to be that the mx.rpc.xml.XMLDecoder class unpacks simple types, but at the point where getSimpleValue() is called, 'value' has already been transformed to the raw data (in this case '5'). However, in the getSimpleValue and getValue methods, the 'value' (revealingly passed in with the parameter name 'parent') is expected to be XML or XMLList or a ContentProxy. So the raw data is right there in the input parameter, but the code falls through all of the cases and returns a result of 'undefined'.
Steps to reproduce:
1. In FlashBuilder 4, use 'Connect to web service' to generate code from the wsdl
2. write a simple UI to pass two numbers to the web service
3. observe that the data in the 'Sum' object is always "NaN" (the marshallBuiltInType() method converts "undefined" double to the 'not a number' value).
Actual Results:
NaN
Expected Results:
5 (or the correct sum)
Workaround (if any):
None that I know of other than getting the XML soap response and interpreting it manually, but that's kind of ridiculous.
