[BUG] IEnumerable<int?> get mapped incorrectly.

[DumboJet]

What is the bug?

When your document contains a field of type IEnumerable<int?> (or any other IEnumerable<Nullable<T>> apparently) it gets mapped incorrectly when auto-mapping. Instead of an integer type, an object type gets created, that contains the nullable properties.

When mapping a nullable object property like public int? Value { get; set; } the mapper correctly maps this field into an integer.

But when you map an array of nullable objects like public IEnumerable<int?> Values { get; set; } then it maps the nullable class members instead, like this:

What is the expected behavior?

A mapping for an integer gets created instead.

What is your host/environment?
