I'm adding a line in a sublist in a client script and when the sublist doesn't have any entry (and I try to set the first one) I'm getting this error TypeError: Cannot read properties of undefined (reading '0') this is the snippet (in pageInit): newRecord.selectNewLine({ sublistId: 'expcost' }); newRecord.setCurrentSublistValue({ sublistId: 'expcost', fieldId: 'doc', value: expenseReportId }); newRecord.setCurrentSublistValue({ sublistId: 'expcost', fieldId: 'apply', value: true }); newRecord.setCurrentSublistValue({ sublistId: 'expcost', fieldId: 'amount', value: cashSaleCcFee }); newRecord.commitLine({ sublistId: 'expcost' });

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like you're encountering an issue with adding a line to a sublist in a client script when the sublist doesn't have any entries. The error message you're seeing,

TypeError: Cannot read properties of undefined (reading '0')

, typically occurs when you're trying to access a property of an undefined object, in this case, the first entry of the sublist. The issue might be related to the mode in which you're trying to manipulate the sublist. In NetSuite, there are two modes for handling records: Standard mode and Dynamic mode. The

selectNewLine

,

setCurrentSublistValue

, and

commitLine

methods you're using are part of the Dynamic mode. If the record is not in Dynamic mode, these methods might not work as expected. Here's a revised version of your code snippet that ensures the record is in Dynamic mode:

javascript
require(['N/currentRecord'], function(currentRecord){
  var newRecord = currentRecord.get({isDynamic: true});
  newRecord.selectNewLine({ sublistId: 'expcost' });
  newRecord.setCurrentSublistValue({ sublistId: 'expcost', fieldId: 'doc', value: expenseReportId });
  newRecord.setCurrentSublistValue({ sublistId: 'expcost', fieldId: 'apply', value: true });
  newRecord.setCurrentSublistValue({ sublistId: 'expcost', fieldId: 'amount', value: cashSaleCcFee });
  newRecord.commitLine({ sublistId: 'expcost' });
});

In this revised version, the

get

method is called with the

isDynamic

option set to

true

, which ensures the record is in Dynamic mode. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
