You're right, I took a closer look into the generated stub code and in the subclass of AbstractWebService - they've by-passed the usual RPC service/operation behavior and implemented a custom private call() method (and it's in there a new SOAPEncoder is constructed). This service stub really should expose a delegate to the SOAPEncoder. So. I think it's still worth logging a request in Flex Builder for this generated code to be updated in general, but I agree that really SDK-19811 needs to be fixed.
(Note: It seems SDK-19598 has become SDK-19811).

Pete, Thanks for the tip. I can set xmlSpecialCharsFilter on the service, but it doesn't get passed into the encoder. Looking around at the generated code and that in the 3.2 SDK (maybe it's changed for 3.3?) I see that the FlexBuilder-generated code is using a class called WSDLOperation, and doesn't seem to be using Operation at all -- and it's in Operation (as you noted) that the xmlSpecialCharsFilter is passed down. Am I missing something?
