Original fields as they were loaded from data source. If your form has .recid and .url properties defined, the form data will be loaded from remote data source into the .record object. A copy of the record data will be saved into .original object. However, as user changes the data in the form the .record object gets updated. The .original stays the same. You should use this property during run-time and after it was loaded from the server. console.log( w2ui.form.original );
