```
When this annotation, along with javax.inject.Named is found on a class, the runtime must place the bean in a CDI scope such that it remains active as long as NavigationHandler.handleNavigation(javax.faces.context.FacesContext, java.lang.String, java.lang.String) does not cause a navigation to a view with a viewId that is different than the viewId of the current view. Any injections and notifications required by CDI and the Java EE platform must occur as usual at the expected time.
If ProjectStage is not ProjectStage.Production, verify that the current UIViewRoot does not have its transient property set to true. If so, add a FacesMessage for the current viewId to the FacesContext stating @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 UIViewRoot.getViewMap(boolean).

Use of this annotation requires that any beans stored in view scope must be serializable and proxyable as defined in the CDI specification.

The runtime must ensure that any methods on the bean annotated with PostConstruct or PreDestroy are called when the scope begins and ends, respectively. Two circumstances can cause the scope to end.
- FacesContext.setViewRoot(javax.faces.component.UIViewRoot) is called with the new 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 FacesContext.getCurrentInstance() returns a valid instance if it is called during the processing of the @PreDestroy annotated method. The set of methods on 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 ExternalContext returned from that 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 ExternalContext.getSessionMap() is also valid to call.
