Anyone know why a selectLine and/or commitLine would fail on a Client Script? I'm running this snippet and idx is always 0 unless I comment out the bit that sets the line value. N.B. I've been running this in the console and hence the simulation of the Client Script's scriptContext.

require(['N/currentRecord'], function(currentRecord){
  var scriptContext = {currentRecord: currentRecord.get()};
  for (var i = 0; i < 3; i++) {
    scriptContext.currentRecord.selectLine({sublistId: 'item', line: i});
    console.log('idx', scriptContext.currentRecord.getCurrentSublistIndex({sublistId: 'item'}));

    scriptContext.currentRecord.setCurrentSublistValue({
      sublistId: 'item',
      fieldId: 'taxcode',
      value: 316
    });

    scriptContext.currentRecord.commitLine({sublistId: 'item'});
  }
});

hi Chris, I believe this is because selectLine and commitLine only work in Dynamic mode, but your code is getting the record in Standard mode

Thanks but there doesn't seem to be any issue with updating the first line but it just doesn't move on from there.
