Here is a piece of my mapping file:


<class name="Type1" table="TST.ENT">
<composite-id name="CompsiteId" class="TestCompositeId" unsaved-value="any">
<key-property name="Id1" column="_ID_1" type="string"/>
<key-property name="Id2" column="_ID_2" type="string"/>
<key-property name="Key" column="_KEY" type="string"/>
<key-many-to-one name="myObj" class="MyObj" column="UID"/>
</composite-id>

<bag name="links" table="TST.Link" lazy="true" cascade="none" inverse="true">
<key>
<column name="_ID_1" not-null="true"/>
<column name="_ID_2" not-null="true"/>
<column name="_KEY" not-null="true"/>
</key>
<one-to-many class="Type2"/>
</bag>
<property name="ts" column="TS" type="java.sql.Timestamp" not-null="true"/>
</class>

<class name="Type2" table="TST.Link">
<composite-id name="CompsiteId" class="Test2CompositeId" unsaved-value="any">
<key-property name="Id1" column="_ID_1" type="string"/>
<key-property name="Id2" column="_ID_2" type="string"/>
<key-property name="Key" column="_KEY" type="string"/>
<key-many-to-one name="myObj" class="MyObj" column="UID"/>
</composite-id>

<bag name="ents" table="TST.ENT" lazy="true" cascade="none" inverse="true">
<key>
<column name="_ID_1" not-null="true"/>
<column name="_ID_2" not-null="true"/>
<column name="_KEY" not-null="true"/>
</key>
<one-to-many class="Type1"/>
</bag>

<property name="ts2" column="TS2" type="java.sql.Timestamp" not-null="true"/>
</class>


When I have a Type1 object and I use Type1.getLinks(), I have these traces back:

- SQL Error: 1006, SQLState: 72000
- ORA-01006: bind variable does not exist

- SQLException initializing collection

Yes, you are right. There is an obvious bug in your mapping. Collection foreign <key>s must have the same number of columns as the primary key of the owning class. Clearly.

Thanks for your respond gavin.
But I'd like Type1.getLinks() return all Type2 objects, whatever UID value is.
Do you have an idea to do that ?

Use a query, not a collection mapping.
