I’ve posted on a few forums now with no results so I’m resorting to my own blog. What I’m trying to do is pass a structure to a ColdFusion component from Flash. I’ve tried using Array, Object, and Dictionary types but it keeps failing with this error:

“Unknown object type tag (17)”

The error seems to be returned before the method is even reached suggesting that the cfc is rejecting the Remoting request altogether. I know the code is sound because I can change the structure to a string and get results back. I’ve also tried the Flash.Params method.

I’ve done a fair amount of research already, including studying Adobe livedocs which insists that it’s possible to do.

Here is my code:

loadData_btn.addEventListener(MouseEvent.MOUSE_DOWN, loadData)

var myService = new NetConnection()
myService.connect("http://localhost/flashservices/gateway/")

function loadData(evt:MouseEvent){
    var responder = new Responder(getTest_Result, onFault);
/* I've tried everything here including defining it as an Object and Dictionary. I also tried
defining it using dot notation and sending it as an object like so: {mystring:"hello"} */
	var mystruct:Array = new Array();
	mystruct["mystring"] = "hello";
	myService.call("com.mycomponent.test", responder, mystruct);
}

function getTest_Result(result){
    trace("success: "+ result);
}

function onFault( f){
	trace("There was a problem: " + f.description);
}

…and here’s my component function (I’ve tried with an argument type of ‘struct’ as well as ‘any’):

Thanks in advance for any help!

SOLUTION: After many hours of Googling, and much trial and error, I figured out how to make this work…and it’s a one line solution. Simply add myService.objectEncoding=0 before the myService.connect line at the top. It has to do with the way objects are serialized using AMF.

Why Adobe left the AS2 Remoting files out of the CS3 installation is beyond me. I work with a countless number of files that utilize AS2 remoting. I don’t have the time to convert them all to AS3 and I think it’s silly to keep Flash 8 on my machine simply because I have to compile files that utilize remoting.

So here, step by step, is what worked for me on Windows XP (another reply to the same thread stated that anyone running Vista should interpret C:\Documents and Settings\YOURUSERNAME\Local Settings\Application Data\… as
C:\Users\YOURUSERNAME\AppData\Local\…. Sorry Mac users, I have nothing against your OS, I just don’t know it):

1. Copy Remoting and RPC Folders from your Documents and settings location TO FLASH CS3 LOCATION.

C:\Documents and Settings\YOURUSERNAME\Local Settings\Application Data\Macromedia\Flash 8\en\Configuration\Classes\mx
to
C:\Documents and Settings\YOURUSERNAME\Local Settings\Application Data\Adobe\Flash CS3\en\Configuration\Classes\mx

2. Copy Remoting.Fla From.

C:\Documents and Settings\YOURUSERNAME\Local Settings\Application Data\Macromedia\Flash 8\en\Configuration\Libraries
To
C:\Documents and Settings\YOURUSERNAME\Local Settings\Application Data\Adobe\Flash CS3\en\Configuration\Libraries

3. Copy NetConnection Debugger.swf and Service Browser.swf from.

C:\Documents and Settings\YOURUSERNAME\Local Settings\Application Data\Macromedia\Flash 8\en\Configuration\WindowSWF
To
C:\Documents and Settings\YOURUSERNAME\Local Settings\Application Data\Adobe\Flash CS3\en\Configuration\WindowSWF

4. Copy NetConnection Debugger.swf and Service Browser.swf from or WindowSWF folder. Note that this is not the same step as the one above. The folders are different.

C:\Program Files\Macromedia\Flash 8\en\First Run\WindowSWF
To
C:\Program Files\Adobe\Adobe Flash CS3\en\First Run\WindowSWF

5. Copy the Libraries Folder.

C:\Program Files\Macromedia\Flash 8\en\First Run
to
C:\Program Files\Adobe\Adobe Flash CS3\en\First Run

6. Copy Remoting and RPC Folders from your Program Files location TO FLASH CS3 LOCATION.

C:\Program Files\Macromedia\Flash 8\en\First Run\Classes\mx
To
C:\Program Files\Adobe\Adobe Flash CS3\en\First Run\Classes\mx

7. Copy the RemotingConnector.swc from.

C:\Program Files\Macromedia\Flash 8\en\First Run\Components\Data Components
to
C:\Program Files\Adobe\Adobe Flash CS3\en\Configuration\Components\Data

8. Copy DataRange.as, PageableList.as, and PageableData.as
C:\Program Files\Macromedia\Flash 8\en\First Run\Classes\mx
To
C:\Program Files\Adobe\Adobe Flash CS3\en\First Run\Classes\mx
AND
C:\Documents and Settings\YOURUSERNAME\Local Settings\Application Data\Adobe\Flash CS3\en\Configuration\WindowSWF

If you’ve done all of that properly you should be able to publish AS2 files that utilize remoting using Flash CS3.

Thanks again to jedders!
