Hibernate version:
3.1
Mapping documents:
Post -> Author
Code:
<many-to-one name="author" class="com.foo.model.Author" cascade="none" outer-join="auto" update="true" insert="true" column="post_author_id" />
Author -> Permission
Code:
<set name="permissions" lazy="true" cascade="delete" sort="unsorted">
<key column="permission_author_id"></key>
<one-to-many class="com.foo.model.Permission" />
</set>
Code between sessionFactory.openSession() and session.close():Code:
public void update(Post post, Integer[] categoryIds) throws DAOException
{
try
{
Session session = getSession();
session.update(post);
post.getCategories().clear();
for (Integer categoryId : categoryIds)
{
Category category = (Category) session.get(Category.class, categoryId);
if (category != null) post.getCategories().add(category);
}
}
catch (HibernateException e)
{
logger.fatal(Messages.getString("errors.hibernate-update"), e);
throw new DAOException("errors.hibernate-update", e);
}
}

I'm had a hunt around the forum and the net for a solution to this problem but haven't found any solutions that work for me. I recently switched to a session per HTTP request pattern and ever since have been unable to update posts. I get the AssertionFailure on a one-to-many relationship (Author to Permission) from a many-to-one relationship on the object I'm updating (Post to Author). This doesn't happen when I create a new post.
Is this a problem with my mapping or a bug in Hibernate?
