Hallo in die Runde,

ich habe eine "many-to-many" mapping das folgender maßen aussieht:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
  <class name="models.Page" table="Page">
    <id column="id" name="Id">
      <generator class="increment"/>
    </id>
    <property column="Name" name="Name"/>
    <many-to-one class="models.Layout" column="layout_id" name="Layout"/>
    <set name="Content" table="Pagecontent_content">
      <key column="page_id"/>
      <many-to-many class="models.Content" column="content_id"/>
    </set>
    <set name="Title" table="Pagetitle_content">
      <key column="page_id"/>
      <many-to-many class="models.Content" column="content_id"/>
    </set>
    <set name="SubMenu" table="Page_submenuitem">
      <key column="page_id"/>
      <many-to-many class="models.SubMenuItem" column="submenuitem_id" not-found="ignore"/>
    </set>
  </class>
</hibernate-mapping>


Ich möchte ein Object speichern welches jeweils zwei "Contents" in "Title" und in "Content" hat. Das funktioniert leider nur halb. Es läuft sauber durch, aber gespeichert sind am Ende nur ein Eintrag aus jeder Liste. Sind zwei oder mehr Einträge in der Liste, werden diese in der entsprechenden Content Tabelle gespeichert, aber leider nicht zur "Page" relation hinzugefügt.

Speichern tue ich folgender mßen.

Code:
            fSessionFactory = new Configuration().configure().buildSessionFactory();
            fSession = fSessionFactory.openSession();
            Transaction tx = fSession.beginTransaction();

            fSession.saveOrUpdate(page.Layout);

            for(int i = 0; page.Content != null && i < page.Content.size(); i++) {
                fSession.saveOrUpdate(page.Content.get(i));
            }

            for(int i = 0; page.Title != null && i < page.Title.size(); i++) {
                fSession.saveOrUpdate(page.Title.get(i));
            }

            for(int i = 0; page.SubMenu != null && i < page.SubMenu.size(); i++) {
                for(int j = 0; page.SubMenu.get(i).Content != null && j < page.SubMenu.get(i).Content.size(); j++) {
                    fSession.saveOrUpdate(page.SubMenu.get(i).Content.get(j));
                }
                fSession.saveOrUpdate(page.SubMenu.get(i));
            }

            fSession.saveOrUpdate(page);

            tx.commit();


Kann mir jemand helfen? Weiss jemand wo das Problem liegt?
