Hi. I have been trying to update a many to many realationship from the inverse entity and i am getting a 'org.hibernate.LazyInitializationException: illegal access to loading collection'. | @ManyToMany(mappedBy = "fleets", fetch = FetchType.EAGER) | public List<User> getUsers() { | return users; | } | | public void setUsers(List<User> users) { | // Add users to relation | if (users != null) { | for (User u : users) { | u.getFleets().add(this); | } | } | | this.users = users; | } | The offending line is u.getFleets().add(this). The user fleets seems to be lazy loaded (i specified EAGER loading on the User entity class) and the Hibernate session discarded.. However i don't know why would the hibernate session be discarded. Doing the same with many to one and one to one relationships worked fine. Also pointers on how else i could be doing this, or pointers to further documentation will be largely apreciated. Thank you, Adrian. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4114669#...
