Editor Samples - joinArray.html has bugs with ServerSide: true.

Mostly, works. Edit joinArray.html and set to serverSide: true. Then click the "permission" column to trigger a sort.

Why does sorting on Permissions break?

var response = new Editor(db, "users", "users.id")
    .Debug(true)
    .Model<JoinModelUsers>("users")
    .Model<JoinModelSites>("sites")
    .Field(new Field("users.site")
        .Options(new Options()
            .Table("sites")
            .Value("id")
            .Label("name")
        )
    )
    .LeftJoin("sites", "sites.id", "=", "users.site")
    .MJoin(new MJoin("permission")
        .Link("users.id", "user_permission.user_id")
        .Link("permission.id", "user_permission.permission_id")
        .Model<JoinAccessModel>()
        .Order("permission.name")
        .Field(new Field("id")
            .Options(new Options()
                .Table("permission")
                .Value("id")
                .Label("name")
            )
        )
    )
    .Process(Request)
    .Data();

namespace EditorNetCoreDemo.Models
{
    public class JoinModelUsers
    {
        public string first_name { get; set; }

        public string last_name { get; set; }

        public string phone { get; set; }

        public int site { get; set; }

        public int manager { get; set; }
    }

    public class JoinModelSites
    {
        public string name { get; set; }
    }

    public class JoinAccessModel
    {
        public int id { get; set; }

        public string name { get; set; }
    }
}

JS

$('#example').DataTable({
    ajax: {
        url: '/api/joinArray',
        type: 'POST'
    },
    processing: true,
    serverSide: true,
    columns: [
        { data: 'users.first_name' },
        { data: 'users.last_name' },
        { data: 'sites.name' },
        { data: 'permission', render: '[, ].name' }
        ]
