Andrew,
Your mapping an integer for theCusstomerType to a customerType object, and
obviously, Castor is unable to convert from integer to the customer type. I
believe that the mapping for theCustomerType should use a sql-many mapping
(this is the appropriate mechanism for mapping a 1-1 as well as a 1-m)
instead of mapping the integer directly:
<field name="theCustomerType"
type="com.vwfs.CustomerType"
get-method="getCustomerType"
set-method="setCustomerType"
required="true">
<sql many-key="customer_type_id"/>
</field>
Hope this helps -
Margaret
