Map nested collection results in a list with one empty class instance instead of empty list

[alessandrosaitta]

Hi, I don't know if I'm missing something but this behaviour seems strange to me.
I take one of slapper examples:

public class Customer
{
	public int CustomerId;
	public string FirstName;
	public string LastName;
	public IList<Order> Orders;
}

public class Order
{
	public int OrderId;
	public decimal OrderTotal;
	public IList<OrderDetail> OrderDetails;
}

public class OrderDetail
{
	public int OrderDetailId;
	public decimal OrderDetailTotal;
}

I change the data of the example to not have an OrderDetail

var dictionary = new Dictionary<string, object>
	{
		{ "CustomerId", 1 },
		{ "FirstName", "Bob" },
		{ "LastName", "Smith" },
		{ "Orders_OrderId", 1 },
		{ "Orders_OrderTotal", 50.50m },
		{ "Orders_OrderDetails_OrderDetailId", DBNull.Value },
		{ "Orders_OrderDetails_OrderDetailTotal", DBNull.Value }
	};

var list = new List<IDictionary<string, object>> { dictionary };

// Act
var customers = Slapper.AutoMapper.Map<Customer>(list);

Now I expect to have a Customer with 1 Order and either an empty list of OrderDetails or a null OrderDetails object but instead I get an OrderDetails list with one OrderDetails instance with both OrderDetailId and OrderDetailTotal equal to 0.
Am I missing something? Is there a way that I can use to achieve the result?
In my project I have some complex object with nested list where I have this problem, could you please help me?

Manny thanks,
