Hi there,
I have a problem with inheritance mapping.
It seems that its not possible to use the table-per-subclass
mapping when the super class has a composite id.

This is my mapping file:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<hibernate-mapping package="test1">
<class name="Ingivning" table="INGIVNING" >
<composite-id name="ingivningid" class="test1.IngivningId">
<key-property name="arendeid"/>
<key-property name="ingivningindex"/>
</composite-id>
<version name="version" unsaved-value="undefined" />

<property name="organisation" />
<component name="namn">
<property name="fornamn" />
<property name="efternamn" />
<property name="adress" />
<property name="postnummer" />
<property name ="postort" />
</component>
<property name="ingivartyp" />
<property name="anmarkning" />
<property name="sekretess" />

<many-to-one name="arende" class="Arende" >
<column name="arende_arendeid" not-null="true"/>
</many-to-one>

<joined-subclass name="IngMedIngNr" table="IngMedIngNr">
<key column="arendeid"/>
<key column="ingivningindex"/>

<many-to-one name="ingivare" column="id" not-null="true" />
</joined-subclass>

<joined-subclass name="IngMedPerNr" table="IngMedPerNr">
<key column="arendeid"/>
<key column="ingivningindex"/>
<many-to-one name="person" column="personid" not-null="true" />
</joined-subclass>
</class>
</hibernate-mapping>

When I run SchemaExport I get an Exception saying that the content of the joined-subclass element must match(meta*,key,(property....blablabla)
And if I change the joined-subclass element so it contains:
<key>
<column="arendeid"/>
<column="ingivningindex"/>
</key>
it complains that element type "null" (i.e. key) must contain either attribute specifications,">" or "/>"

I would really appreciate if someone has the answer to my problem.

Henrik

Not sure if i'm right,
but shouldn't it be:

Thanks!
That solved the problem,
I think I got blind after a couple of hours experimenting!
Anyway, now it works!
Thanks again
