Я работаю над отображением hibernate, и все остальное работало нормально, за исключением PropertyAccessException, которое я получаю, когда hibernate пытается сохранить мой объект в системе. ниже трассировка стека

вот код методов получения и установки 

public String getUuid() {
    return uuid;
}

public void setUuid(String uuid) {
    this.uuid = uuid;
}

и часть отображения 

<id name="uuid" type="java.lang.String">
    <column name="UUID" />
    <generator class="uuid"/>
</id>

Я новичок в спящем режиме, поэтому не очень хорошо представляю, в чем именно заключается проблема, у моего класса назначения есть ссылки на несколько других классов, которые также становятся постоянными, когда я сохраняю класс Destination

любая помощь в этом отношении очень ценится

Edit1

Что ж, похоже, проблема связана с отношением, которое я определил в классе Destination, а также в файле отображения. 

private Set<PlaceToVisit> placesToVisit=new HashSet<PlaceToVisit>();

public Set<PlaceToVisit> getPlacesToVisit() {
    return placesToVisit;
}

public void setPlacesToVisit(Set<PlaceToVisit> placesToVisit) {
    this.placesToVisit = placesToVisit;
}

public void addPlaceToVisit(PlaceToVisit placeToVisit){
    placeToVisit.setDestination(this);
    this.placesToVisit.add(placeToVisit);
}

также в файле сопоставления как 

<set name="placesToVisit" table="PLACETOVISIT" inverse="false" lazy="true" cascade="save-update">
    <key>
        <column name="DESTINATIONID" />
    </key>
    <one-to-many class="PlaceToVisit" />
</set>

пока у меня есть ученики в классе PlaceToVisit 

<id name="uuid" type="java.lang.String">
    <column name="UUID" />
    <generator class="uuid"/>
</id>

<property name="name" type="java.lang.String">
    <column name="NAME" />
</property>

<many-to-one name="destination" class="Destination" fetch="join">
    <column name="DESTINATION" />
</many-to-one>

и другие методы установки для этого класса

когда я удаляю все ссылки на ассоциации из целевого класса, все работает нормально, но добавляю любую запись отношения в файл отображения Destination, показывая мне вышеописанную ошибку.

Эта ошибка может быть вызвана тем, что объект другого типа был найден там, где ожидался объект типа Destination.

Например, если какой-то другой класс был случайно добавлен в Collection<Destination> с помощью непроверенного приведения.
