Flex Monkey Patches

One of my first blog posts pointed to a dev center article that I wrote on this topic for the Flex 2 release. I often send customers to look at this article when appropriate as it is a good starting point for webservice and remoteobject communication between Flex and Coldfusion. I also find myself referring to this sample once in a while and so I have finally decided to host the sample and cfc from my website/blog and potentially enhance the cfc to support more use cases for subsequent blog posts.

            import mx.controls.Alert;
           
            [Bindable]
            public var sResult:String;
               
            public function handleStringResult(event:ResultEvent):void{
                sResult=event.result as String; 
            }
           
        ]]>
    </mx>
       
    <mx :WebService id="myService"
        useProxy="false"
        wsdl="http://739saintlouis.com/services/HelloWorld.cfc?wsdl"
        showBusyCursor="true">     
        <mx peration name="sayHelloString" result="handleStringResult(event)" fault="Alert.show(event.fault.message)"/>
    </mx>
    <mx :Label id="lblStringResult" text="{sResult}"/> 
    <mx :Button label="get String via Webservice" click="myService.sayHelloString.send()"/>

I wrote this article for the Flex 2.0 release.
It is a good intro on how you can move data between Coldfusion 7.02 CFCs and Flex 2.0 using Web Services or Remote Object calls.

My co-worker, Lin Lin, blogged a good follow up to this article that expands up on the configuration and steps necessary to access cfcs on your Coldfusion server from a flex app on a separate server.
