Nhibernate Duplicate data is coming coming, mapping issue

Я застреваю с проблемой в nHibernate.I есть представление, которое имеет несколько записей в таблице, соответствующей одному идентификатору уведомления. Например, для уведомления id = 1 несколько записей есть:Nhibernate Duplicate data is coming coming, mapping issue

При получении записей первая строка, соответствующая идентификатору уведомления, получает дублирование. Например, для уведомления id = 1 есть три строки. Если выборка записей 2-й и 3-й строки имеет те же данные, что и первая строка.

Ожидаемое поведение. NHibernate видит, что вторая и третья записи имеют одинаковый идентификатор, поэтому данные должны быть одинаковыми (id = identity). Он просто передает ссылку на уже созданный первый объект.

То, что вы действительно здесь есть один-ко-многим ассоциации стоимости объектов вместо накидной подкласса, поэтому модель его как:

class vwNotificationPolicyDeliveryCoverLetters : EmailNotificationBase 
{ 
    public virtual Notification Owner { get; set; } 

    //other properties 
} 

<class name="VwEmailNotification" table="`VwEmailNotification`" /> 
    <composite-id> 
    <key-many-to-one name="Owner" column="`notification_id`" /> 
    <key-property name="PolicyNumber" column="`PolicyNumber`" /> 
    <key-property name="LobCode" column="`LobCode`" /> 
    <key-property name="PolicyEffectiveDate" column="`PolicyEffectiveDate`" /> 
    <key-property name="PolicyId" column="`PolicyId`" /> 
    <key-property name="CarrierName" column="`CarrierName`" /> 
    <key-property name="DocumentType" column="`DocumentType`" /> 
    </composite-id> 
</class>

compositeid по всем свойствам соответствует вашей равной реализации
