Description of problem:

In the javascript i have a column defined as

                    { data: "NEW_ITEM", defaultContent: ''  },

On the server side i have the following call to the editor.

                        response = new Editor(db, Instance, new[] { "UNIT", "PRECID", "SRECID", "SUPPLIER" }).Debug(true)
                            .Model<CSDTMOD>()
                                .Field(new Field("NEW_ITEM").Set( // Exclude the "NEW_ITEM" field
                                .Set(false)) // Set it to be ignored
                            .Process(request)
                            .Data();

The field "NEW_ITEM" does not exist in CSDTMOD or in the table on the database. We are inserting a value on the client side using jquery for each row.
I was under the impression .Set(false) would tell the editor to ignore the field and not include it in the query. Any suggestions on how to resolve this?
