hello is it possible to have 2 columns in a table (Usr) who keep references to different records from another table (Member). I want to move a member from a list to another, without removing and creating a new Member. For example this code: | //Usr u | Tournamentmember t = new Tournamentmember(); | t.setUsr(u); | em.persist(t); | ... | //Tournamentmember t | u.getMembers().remove(t);//delete from one list | u.getArchivedMembers().add(t);//add to new list | make's me to have removed member (t) in members collection too, even if I removed before (it is in both list!!!). Thanks for help This are my table: | @Entity | class Usr{ | private java.util.Collection<Member> members; | private java.util.Collection<Member> archivedMembers; | | @OneToMany(mappedBy = "usr", fetch = FetchType.LAZY) | public java.util.Collection<Member> getMembers() { | return members; | } | | | public void setMembers(java.util.Collection<Member> members) { | this.members= members; | } | | | @OneToMany(mappedBy = "usr", fetch = FetchType.LAZY) | public java.util.Collection<Member> getArchivedMembers() { | return archivedMembers; | } | | | public void setArchivedMembers(java.util.Collection<Member> archivedMembers) { | this.archivedMembers= archivedMembers; | } | | } | | @Entity | class Member{ | @ManyToOne(fetch = FetchType.EAGER) | @NotNull | //@JoinColumn(table="Usr", referencedColumnName = "id") | public com.joyplay.ejb.persistence.Usr getUsr() { | return usr; | } | | public void setUsr(com.joyplay.ejb.persistence.Usr usr) { | this.usr = usr; | } | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059574#...
