Update Model Values

When this phase is reached, all submitted values have been validated and converted to the appropriate local value data type. The processUpdates() method is called on the UIViewRoot component, causing the same method to be called recursively on all components in the component tree with the rendered property set to true, which in turn calls the updateModel() method on the component if its an input component. Calling the updateModel() method sets the property of the application object the component is bound to, if any, to the component’s local value. If the property can’t be set, an error message is queued and the FacesContext renderResponse( ) method is called.

At the end of this phase, the broadcast() method of the source components for all events marked to be processed in any phase or in the Update Model Values phase is called to notify the event handlers. The event handlers may call the FacesContext renderResponse() method, possibly after selecting a new view. If so, the processing continues in the Render Response phase. Alternatively, an event handler may render a response itself and call the FacesContext responseComplete( ) method, in which case the request processing is terminated.
