NonUniqueObjectException while saveorupdate within a transaction
I am working on an application using Struts/Spring/Hibernate. I have struts calling services using spring's declarative transactions which then call the DAO which extends HibernateDAOSupport.
There is no lazy loading for any domain objects or collections. I have an object that has one to many relationships with it's children. The problem I am having is that when I save this object the first time it works fine but when I try to do an update, it fails with a NonUniqueObjectException.
I am calling getHibernateTemplate().saveOrUpdate(object). To further describe what excatly happens, when Object is saved the first time, we store it in the HttpSession. When user attempts to update this, I get it out of the HttpSession and map the modified attribute and call the saveOrUpdate. I donot have a unsave-value defined in my mapping. I can see in the logs that a new hibernate Session is opened before it tried to make the update. But it still gives the message " different object with the same identifier value was already associated with the session". I am copying the logs for reference:
