<result column="EndOfDayReportPaymentId" property="Payment" select="
Payment.GetPaymentByPaymentId" />
Do u have any select statement called Payment.GetPaymentByPaymentId in your
map file?
You r trying to call another select from result map. If there is any section
like
<select id="Payment.GetPaymentByPaymentId" parameterClass="Hashtable"
resultMap="something">
SELECT JUST_ONE_FIELD
FROM TABLE
</select>
try to change id name to just GetPaymentByPaymentId and make sure that
result map of that select will return only one field.
Cheers,
Jakub
