this one helps. The answer to this problem cannot be found in the files above. I just forgot to add the AppPrivilegeMap to the ModelMapper during NHibernateHelper.OnConfigure().
Now the last task is to find out where to put the .Inverse(true), so serializing an object won't result in an exception because of circular reference.

How to convert Fluent NHibernate mapping to NHibernate Built-in Code Based Mapping

How to convert Fluent NHibernate mapping to NHibernate Built-in Code Based Mapping

I wish did fix the issue. I have two classes from example using Fluent NHibernate mapping. Fluent NHibernate mapping is commented and I´m trying to make Code Based Mapping, but still appears ArgumentNullException "Value cannot be null.". How to make it right? , I found the solution already. Mapping should be done this way:
code :
public virtual void Map(ModelMapper mapper)
    {
        mapper.Class<LocalizationEntry>(m =>
        {
            m.ComponentAsId(x => x.Id, n =>
            {
                n.Property(x => x.Culture);
                n.Property(x => x.EntityId);
                n.Property(x => x.Property);
                n.Property(x => x.Type);
            });

            m.Property(t => t.Message, c =>
            {
                c.NotNullable(true);
                c.Length(400);
            });
        });
    }

Does that help After poking around in the source code I realised the problem was that IsOneToMany was checked against the property when defining the set before IsManyToMany. I just needed to define IsOneToMany and it worked without any explicit mappings.
code :
        IsOneToMany((mi, wasDeclared) =>
        {
            var propertyType = mi.GetPropertyOrFieldType();

            return ModelInspector.IsEntity(propertyType);
        });
