Conversation Bug?

[gersonk]

My seam application list all books in a dataTable. The user can edit any book simply by clicking on the 'Edit This Book' button placed at the end of each row... it shows the input boxes and the save button in a modal panel.
When the user finishes updating the book information and clicks on save button, I just want to refresh the dataTable to view the changes were made. I tried using reRender, but it didn't work. For some reason, when the application starts a conversation (@Begin), the reRender does not work. How can I refresh the dataTable?

Book.java

@Name("book")
@Entity
public class Book{

 @Id @GeneratedValue(strategy=GenerationType.IDENTITY)
 private Long id;

 private String title;
 private String isbn;

 public Book(){

 }

 public Long getId() { return id; }

 public String getIsbn() { return isbn; }
 public void setIsbn(String isbn) { this.isbn = isbn; }

 public String getTitle() { return title; }
 public void setTitle(String title) { this.title = title; }

BookingSearchingAction.java

@Name("bookSearchAction")
@Stateful
public class BookSearchingAction implements BookSearching{

 @Logger
 private Log log;

 @PersistenceContext(type = PersistenceContextType.EXTENDED)
 private EntityManager em;

 @DataModel
 private List<Book> books = new ArrayList<Book>();

 @Factory(value = "books" )
 public void initBooks() {
 books = em.createQuery("SELECT a from Book a").getResultList();
 }


 @Remove
 public void destroy() {}

 public List<Book> getBooks() { return books; }
 public void setBooks(List<Book> books) { this.books = books; }

}

BookEditingAction.java

@Name(value = "bookEditingAction")
@Scope(ScopeType.CONVERSATION)
@Stateful
public class BookEditingAction implements BookEditing {

 @Logger
 private Log log;

 @PersistenceContext(type = PersistenceContextType.EXTENDED)
 private EntityManager em;


 @In(required = false)
 @Out(required = false)
 private Book selectedBook;

 @Begin()
 public void selectBook(Book book) {
 this.selectedBook = em.merge(book);
 }

 @End
 public void cancelSelection() {
 }


 @End
 public void removeBook() {
 em.remove(selectedBook);
 }

 @End
 public void saveBook() {
 em.merge(selectedBook);
 }


 @Remove
 public void destroy() {}

 public Book getSelectedBook() { return selectedBook; }
 public void setSelectedBook(Book selectedBook) { this.selectedBook = selectedBook;}

}

You need to refresh the outjected list. E.g. remove the variable from the context so that the factory is called again. This is a FAQ, take a look at the forum history.
