Custom typeHandler dbType

[Michael Schall]

I have created several type handlers.  Inside the the sqlMap.config
file I have told ibatis what types and dbTypes are handled by the
handler.

    <typeHandler
      type="ATG.Money, ATG.Money"
      dbType="Currency"
      callback="ATG.Database.TypeHandlers.MoneyTypeHandlerCallback,
ATG.Database"/>

However when passing or getting either of these types to procedures, I
must still tell the resultMap and the parameterMap that the dbType is
currency.

        <parameterMaps>
                <parameterMap id="proc_Update">
                        <parameter property="Id"/>
                        <parameter property="Amount" dbType="currency"/>
                        <parameter property="EnteredDate"/>
                        <parameter property="EnteredBy"/>
                </parameterMap>
        </parameterMaps>

Am I missing something?  Should this be needed?

Thanks
Mike
