[castor-user] Problem in using db.load when mutilple Columns are used as Primary Key

[Vijayanand Sukumar]

All,

I have a oracle view that I mapped to a Jdo. The view has two columns that
combine to form the identity for the JDO. 

<class name="com.foo.Object" identity="id1 id2" >
...
                <field name="id1" type="long">
                        <sql name="ID1" type="bigint"/>
                </field>
                <field name="id2" type="string">
                        <sql name="ID2" type="bigint"/>
                </field>
</class>

Where id2 may or may not be null in the view.

This object is queried by using 

db.load(com.foo.Object.class,new Complex(new Long(1),new
String("2"),Database.ReadOnly);

This works fine. The problem arises when there is no id2.

I tried using 

db.load(com.foo.Object.class,new Complex(new Long(1),new
String(""),Database.ReadOnly);

Which did not work and tried using 

db.load(com.foo.Object.class,new Complex(new
Long(1),null,Database.ReadOnly);

Which also did not work. 

Can someone please help me on how to specify the nullable field in db.load ?


Thanks

Vijay
