page parameter accesible

[alexeicu]

Hi I'm really new in seam, I'm trying to create a page for display data from an entity like this:

BookEditManager.java

@Name("bookEditManager")
public class BookEditManager {
     @In EntityManager entityManager;
     @Logger     Log log;
     
     private Book book;
     
     private Integer bookId;     
     
     @Create
     public void initEditManager() {          
          log.info(this.bookId);
          
          if (this.bookId != null){
               this.book = entityManager.find(Book.class, this.bookId);
               if (this.book == null){
                    throw new org.jboss.seam.framework.EntityNotFoundException(this.bookId, Book.class);
               }
          }else {
               this.book = new Book();               
          }                    
     }

and the page parameter

<param name="bookId" value="#{bookEditManager.bookId}"/>

When I request the url:

http://localhost:8080/libraryProject/book/BookEdit.seam?bookId=2

In the initEditManager the bookId parameter is null, my question is:

When the initEditManager method is called, the bookId property it already has the value taken from the page parameter?.

Which is the order of execution of this ?

1. Constructor.
2. Set page parameter.
3. Call method annotated with @Create.

Is this correct ?

No, @Create should be prior to setting parameters. Parameters are set via EL so component must be instantiated, which means @Create gets invoked before EL gets evaluated further.
You cannot have bookId injected nor used in EL since it is not a property (no setters nor getters).
