Hi Ian,
So you want the country information to be represented in the base class,
while the airport codes are represented in the extension class, right?
You should be able to do this using a binding of this form:
<structure name="DepartureAirport" value-style="attribute">
<value field="originCountryCode" name="CountryCode"/>
<value field="depAirPortCode" name="LocationCode"/>
</structure>
<structure name="ArrivalAirport" value-style="attribute">
<value field="destinationCountryCode" name="CountryCode"/>
<value field="arrAirPortCode" name="LocationCode"/>
</structure>
(assuming the fields in the Leg class are public or protected; otherwise
you can wrap a <structure type="com.ian.Leg"> around each of the
<values> from the base class).
So rather than defining a separate <mapping> for the base class, you
just embed it into the extension class. That's not the best
representation from the code point of view, but since the code structure
is different from the XML structure you need to adapt to the difference
in the binding.
