Question

I read a lot of document about my problem but suggestions couldn't solve my problem so i forced to open this topic.

My problem is that when i try to save my entity i am getting following error. I added my entity classes. Thanks.

Save code

 @Transactional
@Override
public void saveEmployee(EmployeeTable employeeToSave)
{
    employeeDao.saveOrUpdate(employeeToSave);
}

Answer 1

This issue is raised when mixing the CascadeType.PERSIST which works for the operation that persists an entity(JPA-proprietary), with the using saveOrUpdate.

there are Two Options:

Option1:

adding the below CascadeType to the collection field:

@org.hibernate.annotations.Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE) 

• CascadeType.SAVE_UPDATE is used for save(), update(), and saveOrUpdate(), which are 3 Hibernate-proprietary methods. more on http://docs.jboss.org/hibernate/orm/5.0/javadocs/org/hibernate/annotations/CascadeType.html

Option2:

CascadeType.PERSIST is JPA-proprietary have an effect on persist(). More on: http://www.objectdb.com/api/java/jpa/CascadeType. In case of using JPA you should change your Dao to use persist instead of saveOrUpdate.

employeeDao.persist(employeeToSave);

Answer 2

It's so hard for debuging, I think you have to check 'graduation' object in EmployeeTable entity, Actually It's might be not null but it hasn't stored in database and it's not persist in hibernate, when you save EmployeeTable object it's throwing "object references an unsaved transient instance" exception
