Accessing the content of SWFLoader

Question

In Flex 1.5 it was possible to do the following:
<mx:Application xmlns:mx="
http://www.macromedia.com/2003/mxml">
<mx:Button label="Browse"
click="myLoader.content.browse('myFile')" id="browseButton" />
<mx:Button label="Upload"
click="myLoader.content.upload('
http://localhost:8300/upload.cfm')"
id="uploadButton" />
<mx:Loader source="fileIO.swf" height="10" width="10"
id="myLoader" />
</mx:Application>
(above example is from
http://www.adobe.com/devnet/flex/articles/fp8_features.html)
However, when you try running methods in an swf (compiled
from .mxml in Flex 2) and then call those methods from an SWFLoader
instance's content property, nothing happens. I just get errors.
How can I communicate between my application and an
application loaded in SWFLoader in Flex 2.0?

Man, this is crazy, I have followed the example to a tee,
(well I believe so, but I still get the error:
Error #1034: Type Coercion failed: cannot convert
_ChildApp_mx_managers_SystemManager@101650b1 to MainApp.
On my main app, I have,
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Script >
<![CDATA[
import mx.managers.SystemManager;
private var loadedSM:SystemManager;
private function allowInteraction() : void {
loadedSM = SystemManager(swfChild.content);
private function sendData():void {
ChildApp(loadedSM.application).fromMain.text = toChild.text;
]]>
</mx:Script>
<mx:SWFLoader id="swfChild" source="ChildApp.swf"
init="allowInteraction()" y="60" width="261"/>
<mx:Canvas width="278" height="150">
<mx:TextInput id="toChild" width="200" height="20"/>
<mx:Button click="sendData();" label="Submit" y="22"
/>
</mx:Canvas>
</mx:Application>
On my ChildApp, I have
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Script>
<![CDATA[
public function toParent(): void {
MainApp(MainApp).toChild.text = toMain.text;
//local2(owner).fromChild.text = toMain.text;
]]>
</mx:Script>
<mx:Canvas width="204" height="98" x="10" y="10">
<mx:TextArea id="fromMain" width="200" />
<mx:TextInput id="toMain" width="200" y="32" />
<mx:Button label="submit" x="10" y="62"
click="toParent();" />
</mx:Canvas>
</mx:Application>
does anyone have any idea what is wrong with my sample?
Thanks
