Hehe, that was my originally question when I changed it from objectId to clientRelationshipId :)
I run a test case with same mapping (1:n with 1:1 back-reference and shared FK) with latest from OJB_1_0_RELEASE branch. The test pass without problems.
Maybe the problem is the inheritance, I haven't tried this in my test case.
<class-descriptor
class="model.AdmObject">
<extent-class class-ref="model.client.ClientRelationship" />
<extent-class class-ref="model.client.GenericGroup" />

forget my previous post, the error message isn't clear. Why does OJB lookup 'clientRelationshipId' in class 'ClientRelationship' instead of 'NewClientGroup'?
Could you post the whole stack trace?

When OJB lookup the field 'clientRelationshipId' it's not found in 'model.client.ClientRelationship' class-descriptor.
Do your application really use the new mapping files, do you manipulate
OJB metadata at runtime?

Here are the class descriptors:

Field "clientRelationshipId" was used by a 1:n relationship, so using
an
anonymous key can be problematic. See http://db.apache.org/ojb/docu/guides/advanced-technique.html#How+do+
Try to make this field a normal field in NewClientGroup. If you using
PersistentFieldDirectAccessImplNew as PersistentField implementation in OJB.properties file (default setting), no get/setter needed.
The error message is strange I can't find a typo or incorrect mapping.

OJB currently only joins on the related object primary key (which it

Remember that in Reference or Collection Descriptors it is always
looking for the foreign key.
Hope this helps.
If that is the case, then why is OJB looking in model.client.ClientRelationship for clientRelationshipId? It should
be "joining the objects" on ClientRelationship.objectId and NewClientGroup.clientRelationshipId.
Thanks for the effort so far, I do appreciate it.

Hi Wes,
Is my assumption wrong? In this case:
<reference-descriptor name="clientRelationship" class-ref="model.client.ClientRelationship">
<foreignkey field-ref="objectId"/> </reference-descriptor>
Isn't objectId supposed to be the primary key field of model.client.ClientRelationship?
sorry I'm a little confused after all the posts to this thread. Could you please post the class hierarchy (with all (important) fields of
the
classes, no get/setter) and the actual mapping of the classes again.
regards, Armin
