Hi all,

I try to map the following:

A class A (attributes a_id, b) has a 1:1 association (unidirectional) to class B (attribute b_id). The association is persisted in a join table AB (attributes a_id, b_id, discriminator). The 1:1 association can be found with the aid of the discriminator (lets say discriminator must be 'X'). The incomplete solution (for the mapping file A) might be:

<join table="AB"
        optional="true">
        <key column="a_id"
            unique="true"/>
        <many-to-one name="b"
            column="b_id"
            not-null="true"
            unique="true"
            class="B"/>
    </join>

How can I add the additional condition "discriminator='X'" to the mapping ?

Thanks for any help,
Mike
