        Key: HHH-796
    Summary: Hibernate fails to determine identifier of association inside composite-element in EntityMode.DOM4J when declared with embed-xml="false"
       Type: Bug

     Status: Unassigned

Environment: Hibernate 3.0.5; Windows; MySQL 4.1

Description:
Having the following mapping declaration:

<class name="Parent">
    <id name="id"/>
    <property name="label"/>
    <bag name="associations" table="ASSOCIATION" cascade="all">
        <key column="PARENT_ID"/>
        <composite-element class="Association" node="associations">
            <parent name="parent"/>
            <many-to-one name="child" class="Child" column="CHILD_ID" node="child" embed-xml="false"/>
            <property name="info" column="INFO" type="string"/>
        </composite-element>
    </bag>
</class>
<class name="Child">
    <id name="id"/>
    <property name="info"/>
</class>

Hibernate fails with NullPointerException while constructing Parent/assosiations/child element (in fact while getting an identifier of a Child object) in EntityMode.DOM4J:
