anonymous keys and PK in 1.0.4

["Manukyan, Sergey" <SM...@lear.com>]

Folks,

 

Just stumbled on the issue with using anonymous keys which make a
compound PK of the class.

 

 

<class-descriptor class="com.lear.ojb.beans.AmortizedToolingSchedulePO"
table="SVZATSDTL">

 

      <!-- PK { FK (class="com.lear.ojb.beans.AmortizedToolingSchedule")
} -->

      <field-descriptor name="scheduleId" column="SCHEDULE"
jdbc-type="DECIMAL" length="11" primarykey="true" nullable="false"
access="anonymous"/>

 

      <!-- PK { FK (class="com.lear.ojb.beans.Requisition") } -->

      <field-descriptor name="reqNumber" column="REQ#"
jdbc-type="DECIMAL" length="7" primarykey="true" nullable="false"
access="anonymous"/>

      <field-descriptor name="reqType" column="POTYPE"
jdbc-type="VARCHAR" length="5" primarykey="true" nullable="false"
access="anonymous"/>

      

 

      <reference-descriptor name="amortizedToolingSchedule"
class-ref="com.lear.ojb.beans.AmortizedToolingSchedule"
auto-retrieve="false">

            <foreignkey field-ref="scheduleId" />

      </reference-descriptor>

 

      <reference-descriptor name="requisition"
class-ref="com.lear.ojb.beans.Requisition" auto-retrieve="false">

            <foreignkey field-ref="reqNumber" />

            <foreignkey field-ref="reqType" />

      </reference-descriptor>

      

</class-descriptor>

 

So I have a class that has two references, and using 

 

PersistentBroker.delete(new
AmortizedToolingSchedulePO(amortizedToolingSchedule, requisition))

 

It gives me error:

 

[11:20:38,160] ERROR (PersistenceBrokerImpl) - Cannot delete object
without valid PKs.

 

All references are valid objects... PK are anponymous... so what is
wrong?

 

Thank you in advance,

 

-Sergey

Hi Sergey,

sorry for the late reply. Last week I a had DSL malfunction caused by my 
Internet provider. It seems to be fixed (works again for 20 hours), but 
it could happen that I'm out of business again.

Think this has to do with implementation of "anonymous keys"
http://db.apache.org/ojb/docu/guides/advanced-technique.html#How+do
The new created AmortizedToolingSchedulePO object doesn't have any 
mapped anonymous keys in OJB.

regards,
Armin
