ADF Faces Enhanced Event Handling
Like standard JSF components, ADF Faces command components deliver ActionEvent events when the components are activated, and ADF Faces input and select components deliver ValueChangeEvent events when the component local values change. Though ADF Faces adheres to standard JSF event handling techniques, it also enhances event handling. Unlike standard JSF events, ADF Faces events support Ajax-style partial postbacks to enable partial page rendering (PPR). Instead of full page rendering, ADF Faces events and components can trigger partial page rendering, that is, only portions of a page refresh upon request.
