[castor-user] JDO does castor handle array types?

[Andreas Vombach]

Hello all,
I would like to map a class with an array type member. From the docu it 
is not clear to me if this is possible only for XML or for JDO as well.
The class:

public class test
{
   private Integer id;
   private String[] myarray;
   public test() {}
   public Integer getId()
   { return this.id; }
   public void setId(Integer id)
   { this.id = id; }
   public String[] getMyarray()
   { return this.myarray; }
   public void setMyarray(String[] myarray)
   { this.myarray = myarray; }
}
The mapping file:
<mapping>
 <class name="test" identity="id" key-generator="MAX">
   <map-to table="test"/>
     <field name="id" type="integer">
       <sql name="ID" type="integer" />
     </field>
     <field name="myarray" type="java.lang.String" collection="array">
       <sql name="MYARRAY" type="char" />
     </field>
   </class>
</mapping>
Is the mapping correct? I played with the settings but get an exception 
when I retrieve stored values:

JDO queryException: org.exolab.castor.jdo.DataObjectAccessException:

sion error: could not set value of FieldMolder of

.. and this only if the table contains more than one row. Thanks for 
any help!
