Looks like you need to add a name attribute to the <composite-id> element,
to
specify which property holds the composite id.

Saving Children with composite-id
21/01/03 02:03 AM
I have a composite-id element in a child object:
<composite-id
class="com.comcast.cable.dmc.itd.cct.persistence.CCRRecordPK"
unsaved-value="any">
<key-property column="CCR_ID" length="22" name="ccrId"
type="long"/>
<key-property column="RECORD_NUM" length="22" name="recordNum"
type="long"/>
</composite-id>
The CCRRecordPK class has two properties, ccrId and recordNum, both are
java.lang.Long.
In it's parent, I want to correctly map to this child, but I can't seem to
figure out the mapping - and couldn't find any examples. I have this:
<bag role="mpsList" table="CMCF_MPS" cascade="all"
order-by="record_num">
<key column="CCR_ID" length="22"/>
<one-to-many
class="com.comcast.cable.dmc.itd.cct.persistence.CMCFMps"/>
</bag>
but it doesn't work:

Any help is greatly appreciated.
