Hi, has had a unexpecetd result from a simple mapping. Would expect that
when i create a new transient tournament and a new transient user and add the user to the tournaments participants list the user such be cascade createed with the tournament, when i in my dao call saveOrUpdate with the tournament?
Or such i call parsist in order for the CascadeType.Persist to work...?

Hibernate version: 3.1.3 , Annotations 3.1beta7

In tournament entity:

@OneToMany(fetch=FetchType.LAZY, cascade={CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH})
public Set<User> getParticipants() {
return participants;
}

My dao uses a saveOrUpdate()

Name and version of the database you are using: PostgreSql 8.1.3

if you're using Hiernate core (and not HEM), then yoyu need to cascade SAVE_UDAPTE

@org.hibernate.annotations.Cascade(SAVE_UPDATE)

Thanks for the repley.
