I am getting the following error when I am trying to update some of my records.

org.hibernate.HibernateException: More than one row with the given identifier was found: 3333, for class: com.dao.hibernate.TaskItem

I am doing the update like this


Contact myContact = session.load(Contact.class, new Integer(6));
myContact.setFirstName("new name");
session.update(myContact);
session.flush();
session.clear();

What's the link between taskitem and contact ?

The meaning of the exception is that hibernate is loading an object with an identifier but find multiple objects instead of one : it seems that you identifier is not unique
