Hi, Is it possible to create an EJB query to remove a link to other object in a collection (one to many)? e.g. class A { @OneToMany List listOfB(); } class B { Long id; } I would like to create a query which remove the link to object B which id is 1 from the collection of listOfB in object A but I don't know how. I don't want to remove object B, I just want to remove the link. Thanks, Santoso View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4097243#...
