Re: [castor-dev] How do I handle Multiple elements in the XML map to the same object type in Java.

[Keith Visco]

Balaji,

You're in luck! :-)

There is a new feature in the 0.9.5.3 RC1 that allows you to nest a
class mapping, so you can change the mapping for the company field:

<field name="company" type="ClientData">
  <bind-xml node="element">
    <!-- custom mapping for ClientData -->
    <class name="ClientData"> 
       <field name="name" type="string">
          <bind-xml name="CompanyName"/>
       </field>
       ...
    </class>
  </bind-xml>
</field>
