CDI @Inject Named bean in another named bean

Question

I am using jsf 2.2. I have 2 @Named

     @Named(value = "menuMB")
     @ViewScoped
     public class MenuMB implements Serializable{

     }

---

     @Named(value = "produtoGeralMB")
     @ViewScoped
     public class ProdutoGeralMB  implements Serializable{
       @Inject
       private MenuMB menuMB;
     }

Within the produtoGeralMB I have a method that changes a property of the menuMB, however on the jsf page if I use in an inputText #{menuMB.minhaPropriedade}, after ajax there is no change, if use #{produtoMB.menuMB.minhaPropriedade} works.

I noticed that the CDI works with proxy for the injected object. There is something to which on the page I use #{menuMB.minhaPropriedade} and not #{produtoMB.menuMB.minhaPropriedade}? Why does this happen if there is only one instance of menuMB in remembrance?

Answer 1

Use the annotation javax.faces.view.ViewScoped JSF 2.2 instead of the traditional javax.faces.bean.ViewScoped and everything will work correctly.

In fact, it is recommended to discontinue the use of all annotations in the package javax.faces.bean (which was the default in JSF 2.0):

OF API:

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 javax.faces.view.ViewScoped. The Functionality of this corresponding Annotation is identical to this one, but it is implemented as a CDI custom Scope.

Which can be freely translated into:

The annotations in this package can be deprecated in a future version of this specification because they duplicate features provided by other specifications included in Java EE. Where possible the corresponding annotations of the Java EE specification should be used in preference to these annotations. In this case, the corresponding annotation is javax.faces.view.ViewScoped. The functionality of this corresponding annotation is identical to this, but it is implemented as a custom CDI scope.
