Hello!

I have a many-to-many mapping with a list.

<list name="bestandteil_belegungen table="AS_BELEGUNG_GRUPPEN_HBEZ " >

<key column="OBER_ID" />
<list-index column="unter_id_ord" base="1" />

<many-to-many column="UNTER_ID"
class="Bestandteil_belegungen" />
</list>

If I reorder the elements in the list the index-column (OBER_ID) is not updated but other column (UNTER_ID).

HibernateStatement:
update AS_BELEGUNG_GRUPPEN_HBEZ set UNTER_ID=? where OBER_ID=? and unter_id_ord=?


This behavior produces "unique constraint violations" because UNTER_ID refers to primary-key of the basetable of the view AS_BELEGUNG_GRUPPEN_HBEZ.


How is it possible to make Hibernate update the index column?!
