Hibernate version: hibernate3 beta4

2 mapping documents:
Code:
<hibernate-mapping package="visioconference">
  <class name="MediaSessionLevel" table="mediasessionlevel">
    <id name="SQLId" column="msl_id" type="long" unsaved-value="null">
      <generator class="native"/>
    </id>
    <bag name="bandwidths" table="bandwidth" cascade="all-delete-orphan">
      <key column="msl_id" not-null="true"/>
      <one-to-many class="MediaSessionLevel$Bandwidth"/>
    </bag>
  </class>
  <class name="MediaSessionLevel$Bandwidth" table="bandwidth">
    <id name="SQLId" column="ban_id" type="long" unsaved-value="null">
      <generator class="native"/>
    </id>
    <property name="modifier" column="ban_modifier" type="string" length="31" not-null="true"/>
    <property name="value" column="ban_value" type="long" not-null="true"/>
  </class>
</hibernate-mapping>

Code:
<hibernate-mapping package="visioconference">
  <joined-subclass name="Session" extends="MediaSessionLevel" table="session">
    <key column="msl_id"/>
    <property name="creator" column="ses_creator" type="string" length="63" not-null="true"/>
  </joined-subclass>
</hibernate-mapping>


If i add a MediaSessionLevel that's ok:
m = new MediaSessionLevel();
b = new Bandwidth("m",123);
m.addBandwidth(b);
session.save(m);

But if a create a Session (Session inherits MediaSessionLevel, but doesn't override addBandwidth), i've an exception:
s = new Session();
b = new Bandwidth("m",123);
s.addBandwidth(b);
session.save(s);

Full stack trace of any exception that occurs:

Fixed in CVS, please test.
