Partial Processing and Partial Rendering (original) (raw)

The JavaServer Faces lifecycle spans all of the execute and render processes of an application. It is also possible to process and render only parts of an application, such as a single component. For example, the JavaServer Faces Ajax framework can generate requests containing information on which particular component may be processed and which particular component may be rendered back to the client.

Once such a partial request enters the JavaServer Faces lifecycle, the information is identified and processed by ajavax.faces.context.PartialViewContext object. The JavaServer Faces lifecycle is still aware of such Ajax requests and modifies the component tree accordingly.
