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

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34621#action_34621 ] 

Steve Ebersole commented on HHH-1352:
-------------------------------------

There are internal details, but the basic difficulty here is that "read only" is tracked on the o.h.engine.EntityEntry class.  EntityEntry is only created and tracked for *initialized* entities.  Proxies currently have no way to track there "read only" state.  Your patch is making the assumption that the whole entire session will be in "read only" (at least when the proxy data is being fetched).

So either we need to decide if it is better to:
1) add an "entry" object that describes proxies (largely it would be a placeholder for data that needs to transfer over to the EntityEntry after fetch).
2) create an entity entry instance for proxies.

> 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
