Suitelet Select field values are not selectable after using field.addSelectOption method to add select options.

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that the issue is related to the use of the

addSelectOption

method in SuiteScript. When you add select options to a sublist field in a Suitelet, it seems that the options are added for all lines, not just the current one. This can cause issues when the options for a field on one line are dependent on the value of another field on the same line. One solution suggested in the conversations is to not filter the select options, but instead validate the selected option either on

validateField

or

validateLine

, depending on what works best for your workflow. This way, you can ensure that the selected option is valid without affecting the options on other lines. Another solution is to use the

getField

method of the

currentRecord

object to get the field, and then use the

insertSelectOptions

and

removeSelectOptions

methods to add and remove options. However, it seems that there might be some issues with getting the correct ID for the field. One suggestion is to prefix your field IDs with

custpage_

. Here is a code sample from the conversations:

javascript
/**
 * @NApiVersion 2.x
 * @NScriptType Suitelet
 * @NModuleScope SameAccount
 */
define(["N/ui/serverWidget", "N/url", "N/search"], function(serverWidget) {
  return {
    onRequest: function(context) {
      log.debug("context", context);
      var request = context.request;
      var response = context.response;

      var form = serverWidget.createForm({ title: "Hi David" });

      var finishingOptionField = form.addField({
        id: "custpage_finishing",
        type: "select",
        label: "Finishing"
      });
      finishingOptionField.layoutType = serverWidget.FieldLayoutType.NORMAL;
      finishingOptionField.isMandatory = true;
      
      form.clientScriptModulePath = '/SuiteScripts/client.js'

      response.writePage(form);
    }
  };
});

javascript
/**
 * @NApiVersion 2.x
 * @NScriptType ClientScript
 * @NModuleScope Public
 */
define(["N/currentRecord"], function(currentRecord) {
  return {
    pageInit: function(context) {
      context.currentRecord
        .getField({ fieldId: "custpage_finishing" })
        .removeSelectOption({
          value: null
        });
    }
  };
});
