The FOEX Plugin Framework is built on top of Oracle Applications Express (APEX), leveraging the APEX Plugin Interface. New features and design patterns have lately been introduced to allow you to build complex single-page applications (SPA) declaratively.
This plugin is Ajax centric, meaning that everything is refreshable: navigation, menu items, display items, select lists, static regions, forms and the list goes on.
It is also event based, meaning that it allows to respond to a comprehensive set of component events to perform targeted actions, with dynamic action wait for result baked in to all AJAX calls.
