删除的实体查询后出现在relatedentitylist中

使用devforce 7.2.2时，我认为在relatedentitylist中有一个bug。

场景:我调用一个RPC方法，它加载一个实体，包括它的一个相关实体列表。删除子集合中的一个项，然后重新加载数据。使用默认的QueryStrategy，我希望在relatedentitylist中看不到被删除的实体。但它就在那里，并且处于已删除状态。

这个行为是预期的吗?

[AllowRpc]
public static void DoStuff(IPrincipal principal, EntityManager entityManager, params Object[] args)
{
    var id = (int)args[0];
    // Load of one EntityA and his RelatedEntityList of EntityB
    var queryEntitiesA = new EntityQuery<EntityA>().With(entityManager).Include(EntityA.EntityPropertyNames.EntitiesB);
    var entityA = queryEntitiesA.FirstOrDefault(m => m.Id == id);
    // Count == 3
    var count = entityA.EntitiesB.Count(); 
    // Delete of one specific EntityB of the collection
    var entityB = queryEntitiesA.EntitiesB.FirstOrDefault(md => md.Type == 1);
    entityB.EntityFacts.Delete();
    // Now Count == 2
    count = entityA.EntitiesB.Count(); 
    // Reexcution of the query with a new condition which include the EntityA previously loaded
    var entities = queryEntitiesA.Where(p => "condition including the deleted entity").OrderBy(m => m.Date).Execute().ToList();
    // Now the collection is back with a count of 3, including the deleted EntityB. The state of the entity is Deleted
    count = entityA.EntitiesB.Count(); 
}
