Adobe Flex: Accessing Result Event From Main Application In Component MXML - apache-flex

Question

In my main application I have a result event and an XMLList, which is filled with my results. The XMLList is defined outside of a function like so:
public var testList:XMLList = new XMLList();
But within my result handler it is populated with data from the result and it works fine. I need to create an external component MXML file that will contain a List, but from within that component file I can't access testList from the main application.
I have included xmlns:local="*" in each file and my component file also has the following imports:
import mx.collections.XMLListCollection;
import mx.controls.Alert;
import mx.core.Application;
import mx.events.FlexEvent;
import mx.rpc.events.ResultEvent;
I don't understand what I'm doing wrong.

You need to pass the testList as a property of your component.
Main - you have the testList from your result event and your custom component. Pass the testList to a property you've defined in the component, such as data:
<?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"
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:local="*">
<fx:Script>
<![CDATA[
[Bindable]
public var testList:XMLList = new XMLList();
]]>
</fx:Script>
<local:CustomComponent data="{testList}" />
</s:Application>
CustomComponent - from the component you created, access the testList from a property, such as data in this example:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script>
<![CDATA[
[Bindable]
public var data:XMLList;
]]>
</fx:Script>
<s:List dataProvider="{new XMLListCollection(data)}" />
</s:Group>
