/**
 * 

When this annotation, along with * {@code ManagedBean} is found on a class, the runtime must act as if a * <managed-bean-scope>view<managed-bean-scope> * element was declared for the corresponding managed bean.

*
*

If ProjectStage is not * ProjectStage.Production, verify that the current {@code * UIViewRoot} does not have its {@code transient} * property set to {@code true}. If so, add a FacesMessage * for the current {@code viewId} to the FacesContext * stating {@code @ViewScoped} beans cannot work if the view is marked * as transient. Also log a Level.WARNING message to the * log. If ProjectStage is * ProjectStage.Production, do not do this * verification.

*

The bean must be stored in the map returned from * {@code javax.faces.component.UIViewRoot.getViewMap(boolean)}.

*

The runtime must ensure that any methods on the bean annotated * with {@code PostConstruct} or {@code PreDestroy} are called when the * scope begins and ends, respectively. Two circumstances can cause the * scope to end.

*
    *
  • {@code FacesContext.setViewRoot()} is called with the new * {@code UIViewRoot} being different than the current one.

  • *
  • The session, that happened to be active when the bean was * created, expires. If no session existed when the bean was created, * then this circumstance does not apply.

  • *
*

In the session expiration case, the runtime must ensure that * {@code FacesContext.getCurrentInstance()} returns a valid instance if * it is called during the processing of the {@code @PreDestroy} * annotated method. The set of methods on {@code FacesContext} that * are valid to call in this circumstance is identical to those * documented as "valid to call this method during application startup * or shutdown". On the {@code ExternalContext} returned from that * {@code FacesContext}, all of the methods documented as "valid to call * this method during application startup or shutdown" are valid to * call. In addition, the method {@code * ExternalContext.getSessionMap()} is also valid to call.

*

The annotations in this package may be * deprecated in a future version of this specification because they * duplicate functionality provided by other specifications included in * JavaEE. When possible, the corresponding annotations from the * appropriate Java EE specification should be used in preference to * these annotations. In this case, the corresponding annotation is * {@code javax.faces.view.ViewScoped}. The functionality of this * corresponding annotation is identical to this one, but it is * implemented as a CDI custom scope.

*
* * @since 2.0 */ @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.TYPE) @Inherited public @interface ViewScoped { }
