I try to create a list and that works. But sometimes hibernate make a mess of the index in the list. At leats that's what i see in the database. records in the samelist with the same index.
So when i reboot the application the list is "not valid" any more and i really need that index. The problem is that it happens sometimes and sometimes i goes right. somebody an idea?

Hibernate version: 1.2

Mapping documents:
<list name="Items" inverse="false" lazy="false" > <!-- when i use inverse true it never works -->
<key column="PlaylistPeriodId" />
<index column="Position" />
<one-to-many class="DStudioObject.NHibernate.Objects.PlaylistItem, DStudioObject" />
</list>

<many-to-one name="Period" class="DStudioObject.NHibernate.Objects.PlaylistPeriod, DStudioObject" column="PlaylistPeriodId" update="true" insert="true" lazy="false" />

Code between sessionFactory.openSession() and session.close():

here i try different combinations. there for some rules are comment.
