Adobe AIR/Flex Not Receiving Push

I have the following test project and cannot get the server to push anything back to my Adobe AIR client. Here is my code:

SimpleListener.as

package
{
import com.exadel.flamingo.flex.components.flamingo.push.FlamingoListener;
import com.exadel.flamingo.flex.components.flamingo.push.FlamingoMessage;

import mx.controls.Alert;

public class SimpleListener implements FlamingoListener
{
public function onException(exception:Object):void
{
Alert.show(exception.toString(), "Exception");
}

public function onMessage(message:FlamingoMessage):void
{
trace(message.getPayloadData());
}
}
}

FlamingoTest.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication
xmlns:mx="http://www.adobe.com/2006/mxml"

xmlns:client="com.exadel.flamingo.flex.components.flamingo.push.client.*"
creationComplete="init();"
showStatusBar="false">

<client:FxClientSideBroker id="broker" startOnCreate="false" />

<mx:Script>

import com.exadel.flamingo.flex.components.flamingo.push.FlamingoDestination;
import com.exadel.flamingo.flex.components.flamingo.push.FlamingoPushConfiguration;

private static const SERVER_CONTEXT_URL:String = "http://myjbossserver/DataServices";

private function doPush():void
{

FlamingoPushConfiguration.server = FlamingoPushConfiguration.SERVER_SEAM;
FlamingoPushConfiguration.protocol = FlamingoPushConfiguration.PROTOCOL_HESSIAN;

broker.pollingServletURL = SERVER_CONTEXT_URL + "/poll";

var listener:SimpleListener = new SimpleListener();
var dest:String = "test";

var destination:FlamingoDestination = FlamingoObjectsFactory.createDestination(dest);
broker.subscribe(destination, listener);

broker.start();
}

private function init():void
{
doPush();
}
]]>
</mx:Script>

</mx:WindowedApplication>

I am using Flex SDK 3.2, AIR 1.5, Flamingo 2.1.0, am I missing anything to get this to work?

Thanks,
