Vaadin 6 / 7 / 8 Framework Data Binding
1

Hello. I Jave problem with JPAContainer and @ManyToMany property. I my code I have :



@Entity
public class User
{


    @ManyToMany( cascade = CascadeType.ALL, fetch = FetchType.LAZY )
    @JoinTable( name = "Groups_Users",
        joinColumns = { @JoinColumn( name="user_id" ) },
        inverseJoinColumns = { @JoinColumn( name="group_id" ) }
    )
    private List< Group > groups;
}

How create field in form for
groups
 property? I would like to allow Add and Delete elements from list.
I try find soulutions in
com.vaadin.addon.jpacontainer.fieldfactory.FieldFactory
 but in my opinion this class doesn’t support @JoinTable adnotation.

Thank you for any sugesstions :slight_smile:
