This post is to carry on from my previous post regarding moving data from ColdFusion CFCs to Flex 2 Applications Using Webservices.
Here is the first sample showing basic retrieval of a string via Remote Object:
<?
xml version=
"1.0" encoding=
"utf-8"?>
<mx:Application xmlns:mx=
"http://www.adobe.com/2006/mxml" layout=
"vertical" >
<mx:Script>
<!
[CDATA
[
import mx.
rpc.
events.
ResultEvent;
import mx.
controls.
Alert;
[Bindable
]
public var sResult:
String;
public function handleStringResult
(event:ResultEvent
):
void{
sResult=event.
result as
String;
}
]]>
</mx:Script>
<mx:RemoteObject
id=
"myService"
destination=
"ColdFusion"
source=
"services.HelloWorld">
<mx:method
name=
"sayHelloString" result=
"handleStringResult(event)" fault=
"Alert.show(event.fault.message)" />
</mx:RemoteObject>
<mx:Label id="lblStringResult" text="{sResult}"/>
<mx:Button label="get String Remote Object" click="myService.sayHelloString()"/>
</mx:Application>

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.

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.
