Re: [eclipselink-users] updatable=false ignored 
Hello Antonio,
The bug linked describes the issue a bit better than I had in my email. The problem is that the insertable tag controls whether the mapping is writable or read-only, not the updatable. You will need to either use both or none until the bug is fixed - it is currently still open. 

Best Regards,
Chris

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.

    related, please feel free to vote for it.

    Subject: [eclipselink-users] updatable=false ignored

    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();
        }
