Re: [flexcoders] Re: Webservice Random Faults
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.

something is going wrong.
We have a CF implementation for webservices (using coldspring) consumed

The end users are randomly encountering Fault events. We are using FLEX

3.5
Here are the details -
faultCode = DecodingError

The same webservice call works 99% of the time. Randomly we encounter
some

I have gone through this URL http://www.judahfrangipane.com/blog/?p=87and
some others with no resolution.
Monitoring the network SOAP packets using Fiddler, we get HTTP 200 OK
response without any error.
We enabled Flash Debug logging with all events to be logegd
into flashLog.txt and we found that the fault is generated internal to
the
framework -
