Banner Evolution provides a rich user experience within Banner by using the ZKGrails plug-in. Through this plug-in we simplify the development of the user interface for everyday developers while still providing the hooks for those savvy web ninjas. The ZK Framework is a RIA AJAX framework that encourages server side development to create rich internet applications. It abstracts AJAX calls for you and allows you to code all of your UI logic in Groovy or Java without having to spend a lot of time worrying about generated HTML/CSS/JavaScript. Through its abstraction it provides the glue necessary to keep all those technologies working in harmony.
