Hi Dougie,
sorry I don't have a clue what's going wrong.
Could you post a test case?
regards,

Subject: DMapImpl how to implement ManageableCollection ?
Hi Armin:
I try to implement ManageableCollection via DMapImpl,but it can't
work.
I don't know what's worng with it. I design a PersonMap class that
extends DMapImpl and implement ManageableCollection, as like:
package com.dsc.nana.domain.organization;
import org.apache.ojb.odmg.collections.DMapImpl;
import org.apache.ojb.broker.ManageableCollection;
import java.util.Iterator;
import com.dsc.nana.persistence.PersistentObject;
public class PersonMap extends DMapImpl implements ManageableCollection{
public PersonMap() {
super();
}
public void ojbAdd(Object anObject)
{
super.getEntries().add(anObject);
}
public void ojbAddAll(ManageableCollection otherCollection)
{
super.putAll((PersonMap) otherCollection);
}
public Iterator ojbIterator()
{
return super.values().iterator();
}
}
And I declare the PersonMap class in repository as :
<class-descriptor
class="com.dsc.nana.domain.organization.PersonMap"
table="OJB_DMAP"
>
<field-descriptor
name="id"
column="ID"
jdbc-type="INTEGER"
primarykey="true"
autoincrement="true"
/>
<field-descriptor
name="size"
column="SIZE_"
jdbc-type="INTEGER"
/>
<collection-descriptor
name="entries"
element-class-ref="org.apache.ojb.odmg.collections.DMapEntry"
collection-class="org.apache.ojb.broker.util.collections.ManageableHashS
et"
>
<inverse-foreignkey field-ref="dmapId"/>
</collection-descriptor>
</class-descriptor>
Then I get error messages as :
