/**
* 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.
*
*
*
*
* @since 2.0
* @deprecated This has been replaced by {@code javax.faces.view.ViewScoped}.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.
