[jboss-user] [EJB 3.0] - ManyToMany prob. with reading lists from entities

Hi, I have got two Entities. Appointment and AppointmentOffer. The relation is @ManyToMany. Appointment.java //bidirektional, inverse Seite | @ManyToMany(fetch=FetchType.EAGER,mappedBy="appointments",cascade=CascadeType.MERGE) | @IndexColumn(name="INDEX_COL") | private List<AppointmentOffer> appointmentOffers= new ArrayList<AppointmentOffer>(); AppointmentOffer.java | //bidirektional, besitzende Seite | @ManyToMany(fetch=FetchType.EAGER) | @IndexColumn(name="INDEX_COL") | private List<Appointment> appointments = new ArrayList<Appointment>(); I have got two jsf-pages. One is first reading the appointmentOffers and then reading the list with appointments from this offers: show_appointment_offers.xhtml | <rich:dataTable value="#{appointmentBeanInst.appointmentOffers}" var="appOffer"> | <rich:column> | <h:outputText value="#{appOffer.id}" /> | </rich:column> | ... | <rich:column> | <h:dataTable value="#{appOffer.appointments}" var="app"> | <h:column> | <h:outputText value="#{app.title}" /> | </h:column> | </rich:column> | </rich:dataTable> The second pages tries to do the same with the appointments: show_appointments.xhtml <rich:dataTable value="#{appointmentBeanInst.freeAppointments}" var="appointment" > | <rich:column sortBy="#{appointment.title}"> | <h:outputText value="#{appointment.title}" /> | </rich:column> | ... | <rich:column> | <h:dataTable value="#{appointment.appointmentOffers}" var="appOffer"> | <h:column> | <h:outputText value="#{appOffer.title}" /> | </h:column> | </h:dataTable> | ... | The problem is that in the second page only one of the appointmentOffers is shown (in the list is only one appointmentOffer). I do not understand this. The only difference between the first and the second page is that appointmentOffer is the owner side. Is that the reason? How can I solve this? Thanks for your hints.
