Hibernate version:
2.1.6
Name and version of the database you are using:
Mysql 4.0.20d
Here is my setup:
I have a User object that has a Set of CustomLayout objects mapped as a one-to-many.
I am having trouble deleting one of the custom layouts from the Set.
Here are my mapping files:
User.hbm.xml

I am using the spring framework with the TransactionTemplate, so here is the code to delete a customLayout from a user:
/**
* @see com.schmoozenews.user.dao.UserDAO#add(com.schmoozenews.user.layout.domain.CustomLayout)
*/
public void delete(final User user, final CustomLayout customLayout) throws HibernateException
{
TransactionTemplate transactionTemplate = new TransactionTemplate(this.transactionManager);
transactionTemplate.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
transactionTemplate.execute(new TransactionCallbackWithoutResult() {
public void doInTransactionWithoutResult(TransactionStatus status) {
try {
user.getCustomLayouts().remove(customLayout);
userDAO.delete(customLayout);
} catch (HibernateException he) {
SessionFactoryUtils.convertHibernateAccessException(he);
}
}
});
}
Here is the userDao.delete(CustomLayout) method:
/**
* @see com.schmoozenews.user.dao.UserDAO#delete(com.schmoozenews.user.layout.domain.CustomLayout)
*/
public void delete(CustomLayout customLayout) throws HibernateException
{
getHibernateTemplate().delete(customLayout);
}
When I call delete(user,customLayout) , I get the following exception:
net.sf.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): 14, of class: com.schmoozenews.user.layout.domain.CustomLayout
