Debugging Deserialization Errors Between AIR and BlazeDS on ColdFusion using ORM

Now that I am using CF + ORM for most of my Flex and AIR projects, I've had a much more difficult time with the deserialization of objects from AS to CF. The errors thrown by BlazeDS are not helpful at all, and not indicative of the true issue. cfgatewayadapter.jar is a closed source, and make it even more difficult, because it is the culprit in these issues. These issues can sometimes take a full day or two to resolve because the only way I've seen to debug is to start removing code line by line until the thing works. Huge waste of time.
The problem stems from the fact that during deserlization CF barfs when something doesnt match. Instead of throwing a useful error, it proclaims the CFC doesnt exist serverside. The developer then has to go through each componenty property-by-property to try to determine where the problem is.
What we need is something more specific to what the actual problem is. I've not found an adequate way to debug this, and it's causing me to seriously considering changing the backend to Groovy + Granite so I can get the control I need. Really, Adobe just needs to open up the source on cfgatewayadapter or put some time into refining it so that it throws accurate errors.
Examing the error below, one would think that the CFC does not exist. However, if you run the same examples from CFML and pass it an instance of StreamProvider it works fine.
[BlazeDS]Error deserializing client message.

does MySQL work by itself? did you try connecting to your
databases with
phpMyAdmin or alike?
also, make sure you do not have several
mysql-connector-xxxxxx.***.bin
(whatever their names are, you know, the jdbc driver files)
of different
versions - make sure there is only ONE, preferably the latest
one,
anywhere on your server. remove any other ones.
if i remember correctly, the exception you get in the error
is usually
caused by incorrect/old mysql connector drivers...

    Is it possible to transfer music between iPhones and iPods with out using iTunes

    Nope.  Both require iTunes on a computer to sync music from.
    Unless the iPod is an iPod Touch and the music was bought from iTunes.  In which case the Touch can simply go to the iTunes App, under Purchased  and download the purchased songs for free.

    worksafe's link with the KeyChain fix is good.
    This usually happens when KeyChain has two entries for the same WiFi network.
    If repair did not work you can follow the manual steps:
    Disconnect WiFi
    Open KeyChain from Applications / Utilities and find your WiFi network entry(ies) and delete all of them.
    Connect to your WiFi again.

  • I downloaded the OS X on my air and I can't use my keyboard and it won't let me restart my computer because it says that the application assistant canceled the shut down, I don't know what to do

    I downloaded the OS X on my air and I can't use my keyboard and it won't let me restart my computer because it says that the application assistant canceled the shut down, I don't know what to do

    When all else fails (it sounds like it has) hold the power button for about 10 seconds. This shuts down the computer. Then tap it to restart. Since it sounds like the OS upgrade began but then failed to perform a restart you may find that the Install Mavericks file is still in the Applications folder and you can try again. Or you might find that you have to redownload. I don't think the installation is going to proceed as if the computer had successfully restarted but I could be wrong (and in this case gladly so for your sake.)

  • How do I transfer ring tones between ipad and non-apple phone using bluetooth

    Can I transfer ring tones between ipad and non-apple phone using bluetooth?

    No. iOS devices do not support file transfers between non-iOS devices over Bluetooth.

  • Offline synchronization using AIR and Blazeds

    hi freinds how we do offline synchronizaton in AIR application using Blazeds ...
    can u please guide me..
    thanks in advance

    Basically, is you use straight PHP, then you do everything yourself, unless you are using a framework written in PHP like AMFPHP.
    So with PHP you typically use Flex HTTPService controls to call your PHP scripts, and the communication is one-way, you call the script and handle the returned data.
    With BlazeDS and AMFPHP, you can use Flex RemoteObject controls for two-way "server push" functionality, like a stock ticker updating automatically without the user doing anything if the price of a stock goes up.
    Backend distributed data just means you have the data elsewhere (not on the user's machine), and it could be distributed (on serveral servers).
    If this post answers your question or helps, please mark it as such. Thanks!

    Document being generated
    Document Currency = USD (Controlling Area Currency)
    Account     LC1 (EUR)      LC2 (EUR)

    Hi Nishant Arora,
    Modify: It works in performing two actions.
    They are: Insert + Update.
    For Example If a record that is exited in database, so you are modifying that record, it updates that particular record.
    Similarly, If the is not existed in the database, you are modifying it, it inserts a new record.
    Update: Update means just it updates the status, I mean it only updates the record. It doesn't inserts any new record if that particular record is not present in the database.
    These are the cases you need to write these statements.
    Syntaxes: :
