JSF 2.2 - @Inject @ThirteenNumber throw NullPointException : I try to work with `@Injection`, so start with a simple example here :

**Interface** 

    public interface NumberGenerator {
        String generateNumber();
    }

**BookService**

    public class BookServices {
    
        @Inject
        @ThirteenNumber
        private NumberGenerator generator;
        
        public Book createBook(String title){
            return new Book(title, generator.generateNumber());
        }
    }

**Book Object** 

    public class Book {
        
        private String title;
        private String isbn;
    
        public Book() {
        }
        
        public Book(String title, String isbn) {
            this.title = title;
            this.isbn = isbn;
        }
        
        //getters and setters
    }

**CDI**

    @Named(value = "injectionTest") 
    @ViewScoped 
    public class InjectionTest implements Serializable {
    
        public void showResult() {
            BookServices bookService = new BookServices();
            Book book = bookService.createBook("Java book");
            System.out.println(book.toString());
        }
        
        //...
    }

**ThirteenNumber Implementation**

    @ThirteenNumber
    public class IsbnGenerator implements NumberGenerator{
        
        @Override
        public String generateNumber(){
            return "13-84333-" + Math.abs(new Random().nextInt());
        }
    }

**Problem**

When i try to call `bookService.createBook("Java book")` it throw a `java.lang.NullPointerException`, in `generator.generateNumber()` i think it not call the right `@Qualifier`, a tried to solve this problem, using this link, http://stackoverflow.com/questions/21363931/java-ee-7-cdi-injection-doesnt-work-sending-nullpointerexception i add all the dependencies but the problem still the same?

Did i miss something?

**Note** i know about http://stackoverflow.com/questions/218384/what-is-a-nullpointerexception-and-how-do-i-fix-it

Thank you.
