That should be it. You now be able to boot up you Lift app, launch the Flex app, click the “Subscribe to ‘notifications’” to start the Notifier Actor and subscribe to the Consumer to the notifications destination. You should then see id number and the time in the text input field get automatically updated every 0.5 seconds. You can the click the “Unsubscribe from ‘notifications’” to stop the Notifier actor and the Consumer to unsubscribe from the notifications destination. Pretty exciting. With these three technologies it’s really easy to automatically push data from the server to the client in real time. This is obviously a trivial example, but I think it should be relatively straight forward to scale this approach up for more sophisticated apps.
