RE: [eclipselink-users] updatable=false ignored
The problem is exactly what Chris is saying.  If both insertable and updatable are false, the mapping will be readonly.
 
EclipseLink currently will not allow you to set a mapping to be insertable and not updatable.
 
The bug that Chris links to explains a bit more.

Hi,

I've updated my code to use Derby 10.5.3.0 and EclipseLink 2.0, but I still have the pb. I don't have both both insertable=false and updatable=false but only updatable=false. Any idea ?

Thanks,
Antonio

Hello,

 

EclipseLink only allows mappings to be writable or read-only.  Mappings marked as both insertable=false and updatable=false will be set as read-only.

Bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=243301 is related, please feel free to vote for it.

 

Best Regards,
Chris

Hi,


I'm using EclipseLink 2.0M4 with Derby 10.5.1.1 and it looks like updatable=false is ignored. I have the following Entity with a title attribute set to updatable=false :

@Entity
public class BookCustomized {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @Column(name = "book_title", nullable = false, updatable = false)
    private String title;
    private Float price;
    private String description;
    private String isbn;
    @Column(name = "nb_of_page", nullable = false)
    private Integer nbOfPage;
    private Boolean illustrations;
...
}

But I can update the attribute. Here is the test case. Any idea ? 
Thanks
Antonio

 @Test
    public void titleShouldNotBeUpdatable() throws Exception {

        BookCustomized book = new BookCustomized("The Hitchhiker's Guide to the Galaxy", 12.5F, "The Hitchhiker's Guide to the Galaxy is a science fiction comedy series created by Douglas Adams.", "1-84023-742-2", 354, false);
        tx.begin();
        em.persist(book);
        tx.commit();
        assertNotNull("ID should not be null", book.getId());
        assertEquals("Title should be The Hitchhiker's Guide to the Galaxy", "The Hitchhiker's Guide to the Galaxy", book.getTitle());

        tx.begin();
        book = em.find(BookCustomized.class, book.getId());
        assertEquals("Title should be The Hitchhiker's Guide to the Galaxy", "The Hitchhiker's Guide to the Galaxy", book.getTitle());
        book.setTitle("H2G2");
        assertEquals("Title should be H2G2", "H2G2", book.getTitle());
        tx.commit();

        tx.begin();
        book = em.find(BookCustomized.class, book.getId());
        assertEquals("Title should be The Hitchhiker's Guide to the Galaxy", "The Hitchhiker's Guide to the Galaxy", book.getTitle());
        tx.commit();
    }
