Почему исчезают поля при накатывании эволюции?

Question

[PaulTes]

Здравствуйте, осваиваю Play Framework Из таблицы исчезают поля created_at и updated_at, когда я накатываю эволюцию. Причем проблема проявляется только на тестовой базе данных, при обычном запуске в dev mod все нормально, поля на месте.

Вот код создания таблицы:

create table if not exists cash_services (
  id                     serial PRIMARY KEY,
  percent_value          numeric,
  calculation_type       int4 not null,
  constant_value         numeric,
  direction              int4 not null,
  owner_type             int4 not null,
  finance_event_id       int4 not null,
  created_at             TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT clock_timestamp(),
  updated_at             TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT clock_timestamp()
);

Вот код ксласса Cash_services:

package entities;

import entities.base.OwnerType;
import entities.base.PersistenceEntity;
import exceptions.FinanceEventException;
import io.ebean.Finder;
import modules.db_convertations.DatabaseAmount;
import play.data.validation.Constraints;
import play.data.validation.Constraints.Required;

import javax.persistence.*;
import javax.validation.Valid;

import java.math.BigInteger;

import static play.data.validation.Constraints.*;

@Validate
@Entity
@Table(name = "cash_services")
public class CashService implements PersistenceEntity, Validatable<String> {

    public static final Finder<Integer, CashService> finder = new Finder<>(CashService.class);

    public enum Direction {
        FROM,
        TO
    }

    public enum CalculationType {
        PERCENT_PLUS,
        PERCENT_MINUS
    }

    @Id
    @SequenceGenerator(name="cash_services_id_seq",
            sequenceName="cash_services_id_seq",
            allocationSize=1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "cash_services_id_seq")
    private int id;

    @Column(name = "percent_value")
    private DatabaseAmount percentValue;

    @Enumerated(EnumType.ORDINAL)
    @Column(name = "calculation_type")
    private CalculationType calculationType;

    @Column(name = "constant_value")
    private DatabaseAmount constantValue;

    @Column(name = "fix_value")
    private DatabaseAmount fixValue;

    @Required
    @Enumerated(EnumType.ORDINAL)
    private Direction direction;

    @Required
    @Enumerated(EnumType.ORDINAL)
    @Column(name = "owner_type")
    private OwnerType ownerType;

    @OneToOne(optional = false)
    @JoinColumn(name = "finance_event_id", referencedColumnName = "id")
    private FinanceEvent createdEvent;


    public void setId(int id) {
        this.id = id;
    }

    public void setPercentValue(DatabaseAmount percentValue) {
        this.percentValue = percentValue;
    }

    public void setCalculationType(CalculationType calculationType) {
        this.calculationType = calculationType;
    }

    public void setConstantValue(DatabaseAmount constantValue) {
        this.constantValue = constantValue;
    }

    public void setDirection(Direction direction) {
        this.direction = direction;
    }

    public void setOwnerType(OwnerType ownerType) {
        this.ownerType = ownerType;
    }

    public void setCreatedEvent(FinanceEvent createdEvent) {
        this.createdEvent = createdEvent;
    }

    public void setFixValue(DatabaseAmount fixValue) {
        this.fixValue = fixValue;
    }

    public int getId() {
        return id;
    }

    public DatabaseAmount getPercentValue() {
        return percentValue;
    }

    public CalculationType getCalculationType() {
        return calculationType;
    }

    public DatabaseAmount getConstantValue() {
        return constantValue;
    }

    public Direction getDirection() {
        return direction;
    }

    public OwnerType getOwnerType() {
        return ownerType;
    }

    public FinanceEvent getCreatedEvent() {
        return createdEvent;
    }

    public DatabaseAmount getFixValue() {
        return fixValue;
    }

    @Override
    public String validate() {
       //Код валидации
        return null;
    }
}

Как видите в классе этих полей нет, т.к. они пока не нужны. Возможно, проблема в этом? Существует ли в Play механизм модификации таблиц по классам. Если да, то как его отключить?
