I am afraid having to do that will defeat the purpose of having webservices in place! To me it alternately looks like having HTTPService with required params to a CF page that queries the db and returns the data back (in your case its via AMF using remoteObj). In-case someone is looking for an answer -
I spent a lot of time trying to dig through the framework api with debug points everywhere. Its unfortunate, i was in a place where finding the cause of the problem was a pain as the faults were not consistent and any code changes cannot be tested without it being reproducible. I read in the comments of this url - http://www.judahfrangipane.com/blog/?p=87 that getting rid of fiddler sometimes avoids these errors. In my case these were not the IO errors (#2032) as i receive the HTTP status codes fine 200 in the response in fiddler. I just couldn't give a straight solution to get rid of fiddler without the issue being reproducible. While i debugged through the framework, i figured out that error was getting generated from mx.rpc.AsyncRequest.as (Line 62) and the acknowledgement forwarded by fiddler has DSErrorHint set to true. This is the catch to isolate why fiddler receives the HTTP status 200 fine (acting as proxy) just that it doesn't reach through till flash player fine. One of the QA Engineers reproduced the problem in-house and I have witnessed having fiddler on (acting as proxy) causes the problem and turning it off gets rid of it [I was really lucky to reproduce it, it was like one out of 30-40 operations faults]. Hard to even convince any one even now, but hope this saves someones time. Use network sniffers instead of http proxies for debugging. ~ Arun On Mon, Feb 22, 2010 at 12:12 PM, valdhor <valdhorli...@embarqmail.com>wrote: > > > I came across multiple problems using Flex's built-in SOAP decoder.
