JSF for Nonbelievers: The JSF Application Lifecycle

Phase 4: Update Model Values
|
|
The fourth phase of the JSF application lifecycle -- update model values -- updates the actual values of the server-side model -- namely, by updating the properties of your backing beans (also known as managed beans). Only bean properties that are bound to a component's value will be updated. Notice that this phase happens after validation, so you can be sure that the values copied to your bean's properties are valid (at least at the form-field level; they may still be invalid at the business-rule level).
