I created a simple Joomla! component. It’s purpose is to demonstrate how a Flex Application can be integrated into a component. The Flex Application is communicating with its Joomla! backend through AMFPHP. AMFPHP1.9 is included in this example setup.
You can download and install this component via the Joomla Administration Interface and link a menu item to it, to see it in action.
You can also download the source code for the simple Flex Application to see how it connects to the gateway.
