Abstract: A system and method for the rapid and visual web-based development of web-based customer service applications which render rich graphical user interfaces emulating the controls common to traditional desktop applications is disclosed. The rich user interface applications are comprised of scripting languages built with standard browser-based protocols and thus do not require the installation of any additional client-side or proprietary software applications. Not only is the user able to work on a rich user interface web application, but this application then allows the user to create, or develop, another web-based rich-thin-client application using visual programming tools.
