Re: OJB Deadlock due to reference descriptor

[Ilkka Priha]

OJB fully supports mapping of several classes to the same table. In this 
case, you'll read the same data into two data structures being kind of 
"reflections" of each other.

I am using OJB with java 1.5 

I have done the following mapping

<class-descriptor
class="applications.dts.models.testcase.testcasegrid.TestCaseGrid"
table="dts.testcaseactions">
        <field-descriptor name="testCaseActionId" column="TestCaseActionID"
primarykey="true" autoincrement="true" access="readonly" />
        <field-descriptor name="testCaseId" column="TestCaseID" />
        <field-descriptor name="affectedInsert" column="InsertFlag" />
        
    	<reference-descriptor

class-ref="applications.dts.models.testcase.testcasegrid.testcaseactions.TCAction"
                auto-retrieve="true"
                auto-update="true"
                auto-delete="true" >
                <foreignkey field-ref="testCaseActionId"/>

    </reference-descriptor>
    
</class-descriptor>


Logically it should be a deadlock but OJB does not throw any exception and
is working fine.
Can anybody elaborate on this why is it working fine Or is there a mistake
in my mapping?
