Moving data from ColdFusion CFCs to Flex 2 Applications Using RemoteObject

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>
 

This movie requires Flash Player 9

Moving data from ColdFusion CFCs to Flex 2 Applications Using Webservices

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.

<?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:WebService id="myService"
        useProxy="false"
        wsdl="http://739saintlouis.com/services/HelloWorld.cfc?wsdl"
        showBusyCursor="true">     
        <mx:operation name="sayHelloString" result="handleStringResult(event)" fault="Alert.show(event.fault.message)"/>
    </mx:WebService>
    <mx:Label id="lblStringResult" text="{sResult}"/>   
    <mx:Button label="get String via Webservice" click="myService.sayHelloString.send()"/>

</mx:Application>
