---------------------------------------

             Summary: @PreDestroy method not invokved on javax.faces.bean.ViewScoped beans
                 Key: MYFACES-4047
                 URL: https://issues.apache.org/jira/browse/MYFACES-4047
             Project: MyFaces Core
          Issue Type: Bug
          Components: JSR-344
    Affects Versions: 2.2.10
            Reporter: Paul Nicolucci
            Priority: Minor


Consider the following scenario:

Bean1:
@Named
@ViewScoped (javax.faces.view.ViewScoped)

Bean2:
@ManagedBean
@ViewScoped (javax.faces.bean.ViewScoped)

When the session is invalidated the org.apache.myfaces.cdi.impl.CDIManagedBeanHandlerImpl.onSessionDestroyed()
method is invoked. Here, MyFaces destroys all of the javax.faces.view.ViewScoped @Named beans
and @PreDestroy is invoked on these beans. However, the @ManagedBean /ViewScoped bean does
not have its @PreDestroy invoked.

I believe this is because the assumption was made that if an Application is CDI enabled it
will contain all CDI @Named beans and not any @ManagedBeans. There is also the DefaultViewScopeHandler
which is not yet implemented for "onSessionDestroyed" that would be used in the case when
CDI is not enabled, that is when only @ManagedBeans are contained in the application.

I believe it is possible to update the CDIManagedBeanHandlerImpl to be aware of the ViewScoped
ManagedBeans and destroy them onSessionDestroy first by just getting the viewMap and iterating
over the entries as we do when the PreDestroyViewMapEvent is processed.

I'd like to use this issue to resolve the problem in CDIManagedBeanHandlerImpl as well as
implement onSessionDestroy in DefaultViewScopeHandler.java
