Hi,
I ended up getting an error, I think it was due to the text "lastResult". Below is the error:
I am very curious to know if someone can try this simple example and get a datagrid to populate via a query object from CF.
Error: Unknown Property 'artists'.

Here is the CFC:
<cfcomponent>
<cffunction name="getArtists" access="remote" returntype="query">
<cfset var artists = '' />
<cfquery name="Artists" datasource="cfcodeexplorer">
SELECT firstname, lastname
FROM ARTISTS
</cfquery>
<cfreturn Artists />
</cffunction>
</cfcomponent>
Here is the current MXML:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="initApp()">
<mx:Script>
<![CDATA[
import mx.rpc.events.*;
import mx.collections.ArrayCollection;
public function initApp():void {
// Force artists class to load
artSvc.getArtists.send();
}
]]>
</mx:Script>
<mx:RemoteObject
id="artSvc"
destination="ColdFusion"
source="myApp.cf.com.artists"
showBusyCursor="true" />
<mx:DataGrid id="dg" dataProvider="{artSvc.getArtists.artists}" x="177" y="65">
<mx:columns>
<mx:DataGridColumn headerText="First Name" dataField="firstName"/>
<mx:DataGridColumn headerText="Last Name" dataField="lastName"/>
</mx:columns>
</mx:DataGrid>
</mx:Application>
