    Hi,

    I’m new to hibernate. I’ve been following a tutorial on the hibernate website. My problem is that an exception is thrown when i try to insert a new record. I have noticed that the exception is thrown on execution of the commit method of the transaction object. The INTERESTING thing that I have noted is tha the record is always saved to the database (MySQL) even when the exception is thrown. here is the stack trace :

    ! inside CREATE!!!
    ! about to save
    about to commit
    net.sf.hibernate.HibernateException: identifier of an instance of com.rdoku.model.User altered from 3 to 3

    I moved your other dupe of this post to OT > Soft dev already, I’m closing this one so people can focus on the other post.
