A very simple MXML Application component to handle server-side messaging

MXML for Messaging

	<!-- The two consumer tags setup the connection to our ActiveMQ topics -->
	<!-- Note how the value of the destination attribute matches our messaging-config.xml destinations -->
	<!-- The selector attribute is used to filter messages in a topic for a specific client. For the purpose of this example, I've hard-coded the value whereas in a real application, we set the .NUMBER dynamically -->
	<!-- The last important attribute are your handlers, of course. Don't forget those :) -->
