Model-View-Controller based Plug-able Declarative Framework

A Model-View-Controller based Plug-able Declarative Framework (MVC-PDF) will be described, in which developers use the full power of ColdFusion MX (CFMX) components to create MVC applications. The declarative nature of the framework will allow the controller and the model to be specified declaratively in configuration files, versus custom coded in ColdFusion. A MVC-PDF will allow develope... (more)
