I use one-to-many mapping of parent child like structure. To store children objects it use list.

/parent/

<list name="array"
inverse="true"
cascade="all,delete-orphan">

<key column="PARENT_ID"/>
<list-index column="listnumber"/>
<one-to-many class="child"/>
</list>


/child/


<many-to-one
name="parent"
column="PARENT_ID"
class="parent"
not-null="true" />


The "listnumber" filed is not mapped in child.

The problem is that listnumber is saved always as a null into db so it can not recreate list object properly from db.
My intension was that position in the list transvers into listnumber value and vice versa.
I belive I missing smth on the child side. Can be that listnumber has to be mapped as a key.

Sincerely,

... I think I got the answere.

proper mapping should looks like

/parent/

<list name="array"
cascade="all,delete-orphan">

<key column="PARENT_ID"/>
<list-index column="listnumber"/>
<one-to-many class="pdbCode"/>
</list>


/child/

<many-to-one
name="parent"
column="PARENT_ID"
class="project"
not-null="false"
insert="false"
update="false" />


For some reason invers="true" is not working with list. Maybe it would be fixed in new version of hibernation.
