Flash Player 8 Mac OS Gateway bug using Flash Remoting and CFMX 7

This is a recorded bug that is solved by the CFMX7 cumulative hot fix 2. However, the bug is still active only on MAC OS X standalone flash player or projector.

Thanks to Dave Stanten at Adobe, for sending me the technote and resolving this issue: Tech Note

ColdFusion MX 7 Gateway Connection URL

If you are using Flash Remoting to access ColdFusion code, you may run into an issue where ColdFusion constructs an invalid URL when appending a jsessionid. If this occurs, the web server that is accessing your code could throw errors. The solution is to simply add a question mark (?) to the end of the gateway URL. Change /flashservices/gateway to /flashservices/gateway?. This ensures that the URL is created correctly.

I only had this problem with flash player 8 and 7 for the MAC, but standalone only. If I used the flash player plugin within a browser I was ok or if I used any form of the flash player on Windows.

Also, the tricky part is that the Coldfusion logs report the following, which is due to the malformed URL’s:

[Flash Remoting MX]->Request received was not Flash-based (not of the binary AMF protocol)

So lookout for this tricky bug if you come upon it. A single character can make a difference.

Happy Remoting!!!

Restart CFMX and you are ready to debug. This is tedious if you need to disable it again. So after a few hours of trial and error and digging through the Actionscript whitepapers, I finally came up with a "ONE LINER" to activate debugging. Let's say for example you have a simple form calling a remote service and the button code is the following:

The "sayhello" variable holds the remoting call:

<cfsavecontent variable="sayhello">
//NetDebuggin ON, That was simple var debug:Boolean = mx.remoting.debug.NetDebug.initialize();

//create gateway connection var connection:mx.remoting.Connection = mx.remoting.NetServices.createGatewayConnection("http://www.luismajano.com/flashservices/gateway/");
//declare service var myService:mx.remoting.NetServiceProxy;
//Create response handler var responseHandler = {};

responseHandler.onResult = function( results: Object ):Void {
alert(results);
}

//function that receives any error that may have occurred during the call responseHandler.onStatus = function( stat: Object ):Void {
//if there is any error, show an alert alert("Error while calling cfc:" + stat.description);
}

//get service myService = connection.getService("utilities.hello", responseHandler );

//make call myService.sayHello();
</cfsavecontent>

And there you go, the NetDebugger will now work. That was a lot of research for one line. Please let me know if you have any other ways of enabling debugging. Thanks.
