[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1352) Session.setReadOnly(Object, boolean) fails for proxies

[Roland Groen (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33966#action_33966 ] 

Roland Groen commented on HHH-1352:
-----------------------------------

There is a workaround (at least to prevent the exception):

PersistenceContext ctx = ((SessionImplementor)session).getPersistenceContext();
if (ctx.getEntry(t) != null) {
   getSession().setReadOnly(t, true);
}

> Session.setReadOnly(Object, boolean) is broken. It throws a TransientObjectException with the message "Instance was not associated with the session" when the object is quite obvious associated with the current session, because we only just loaded it using Session.load(Class, Serializable)
> Here is a simple JUnit test, for an arbitrary entity:
>   public void testReadOnly()
>     throws Exception
>   {
>     User user = (User) session.load(User.class, new Long(7));
>     System.out.println("\n=== " + user + " ===");
>     session.setReadOnly(user, true);
>   }
> This is the exception stack trace:
> org.hibernate.TransientObjectException: Instance was not associated with the session at org.hibernate.engine.StatefulPersistenceContext.setReadOnly(StatefulPersistenceContext.java:1167) at org.hibernate.impl.SessionImpl.setReadOnly(SessionImpl.java:1740) at
> test.persistence.HibernateObjectTest.testReadOnly(HibernateObjectTest.java:30) ....
