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.
