2.11 Understanding How Bindings Are Created at Runtime
To round out this basic introduction of ADF Model binding for JSF pages, it is good to understand how your data controls and declarative bindings are created at runtime. As part of configuring your project for working with Oracle ADF data binding, JDeveloper registers an additional handler that is triggered whenever a client requests a JSP page. This handler is listed in the standard J2EE web application configuration file (web.xml) of your ViewController project. It sets up the correct binding container for the current page based on the related ADF Model XML configuration files, and makes it accessible using the EL expression #{bindings}. During the subsequent handling of the web page request, the JSF standard dictates a predictable set of processing steps known as the page "lifecycle". Oracle ADF uses standard mechanisms to plug into these processing steps to automate preparing data for display, invoking built-in operations or custom service methods, as well as updating and validating data against the view objects in your application module's data model.
