Получение "ноль" при попытке доступа к переменной объекта в mybatis mapper xml

Question

public interface RawProductEvaluationEventDao 
{

public List<ProductEvaluationEvent> getEventsByTypeAndProductEvaluation(
        @Param("evaluation") ProductEvaluation evaluation,
        @Param("eventType") EventType eventType);
}

Это мой картограф xml RawProductEvaluationEventDao.xml

<select id="getEventsByTypeAndProductEvaluation" resultType="ProductEvaluationEvent">
    SELECT
    id, 
    productEvaluationFk, 
    eventTimestamp,
    receiptEventTypeFk,
    isStartEvent,
    isSuccess,
    supplementalEventText,
    exceptionStackTraceText
    FROM
    productEvaluationEvent
    WHERE productEvaluationFk = #{evaluation.id}
    AND receiptEventTypeFk = #{eventType.id}
</select>

Я добавил регистратор и обнаружил, что я получаю нулевое значение как для analysis.id, так и для eventType.id.
