SynapticFaces

The SynapticFaces product is designed to enhance the JSF framework and to make the JSF usable in real world. SynapticFaces is a simple, yet elegant solution that marries JSF with JSX and gives JSF components much needed browser-side functionality as well as ability to make AJAX calls between the client and server.
