Hi all. I went to the Adobe Intro to Flex training for CF developers
this past weekend in Durham. With all this new found goodness, I
wanted to try it out on one of my MG apps.
I'm running CF9, lastest MG3, Flex 4. The current MG3 app is
functioning correctly.
I followed the instructions for using the MG remoting service cfc and
getting the following error.
ReferenceError: Error #1065: Variable stuff is not defined.

Here is the relevant code:
my xmxl file:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009";
xmlns:s="library://ns.adobe.com/flex/spark"

minWidth="1024"
minHeight="768"
creationComplete="init()">
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects)
here
-->
<mx:RemoteObject id="mgrs"
destination="ColdFusion"
source="eRequest.RemotingService"
result="resultHandler(event)"
showBusyCursor="true" />
</fx:Declarations>
<s:layout>
<s:VerticalLayout paddingTop="10" paddingBottom="10"
horizontalAlign="center" />
</s:layout>
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.rpc.events.*;
[Bindable]
public var stuff:ArrayCollection;
public function init():void{
//call Model-Glue Remoting Service cfc
mgrs.executeEvent("requests.ListRequests",{},"qryRequests");
}
public function resultHandler(event:ResultEvent):void{
stuff = event.result.qryRequests as ArrayCollection;
}
]]>
</fx:Script>
<mx:DataGrid dataProvider="stuff" width="90%">
<mx:columns>
<mx:DataGridColumn headerText="Request Number"
dataField="RequestNum"/>
</mx:columns>
</mx:DataGrid>
</s:Application>
My event handler:
<event-handler name="requests.ListRequests"
type="templatedPage">
<broadcasts>
<message name="requests.ListRequests"/>
</broadcasts>
<results/>
<views>
<name name="body"
template="requests/ListRequests.cfm">
<argument name="xe.list"
value="requests.ListRequests"/>
<argument name="xe.edit"
value="requests.EditRequest"/>
</name>
</views>
</event-handler>
My controller:
<cffunction name="getRequests" output="false" hint="I am a message
listener function generated for the ""requests.ListRequests"" event.">
<cfargument name="event" />
<cfset arguments.event.setValue
("qryRequests",beans.requestService.getRequests()) />
</cffunction>
Any ideas of what might be happening? In the debugging I see
references to "http://www.adobe.com/2006/flex/mx"; though the namespace
that is being used is "http://ns.adobe.com/mxml/2009";. Not sure if
that means anything.
Thanks in advance
byron
