g_form.getReference returns an undefined value

[Jon23]

I am currently trying to create a child ticket with all the information from the parent in it.

Using the new button on the related list 'Facilities Request->Parent';

the following client script is triggered:

function onLoad() {


     if(g_form.isNewRecord()){
           var dad = g_form.getValue('parent');
           if(dad != ''){
                 var parentRecord = g_form.getReference('parent');
                 g_form.setValue('opened for', parentRecord.opened_for);
                 g_form.setValue('location', parentRecord.location);


       jslog("JW-DEBUG: " + parentRecord.opened_for);
       jslog("JW-DEBUG: " + parentRecord.location);


           }
     }
}
function onLoad() {


     if(g_form.isNewRecord()){
           var dad = g_form.getValue('parent');
           if(dad != ''){
                 var parentRecord = g_form.getReference('parent');
                 g_form.setValue('opened for', parentRecord.opened_for)

The location field is correctly populated on my child ticket, however, the opened_for is not.

Looking at the javascript log i see the following:

JW-DEBUG: undefined
JW-DEBUG: b466f2800a0a3c7e00b84e0d16c206ae

Both fields are reference fields so I am confused why one works and one does not - any suggestions?

Not confused, makes perfect sense. I did some playing around and got it to work. It was those extra fields fields where it didn't work.

Thanks for taking the time to explain this. I have a greater understanding now.

So how do you deal with those situations then? You have explained what the issue is but have not provided a solution.

Please try below line:

1. g_form.setValue('opened_for', parentRecord.opened_for, parentRecord.opened_for.getDisplayValue());

Hi jwalton, I was having issues with g_form.getReference while testing Helsinki. I was able to resolve by migrating to a client callable script include model. This is preferred over the getReference option anyway because it utilizes Server power and not client. g_form.getReference actually creates a GlideRecord on the client side, and can cause slowness. Try something similar to below.

Carate a new Script Include, (make sure you click the "Client Callable" button).

var sc_getUserData = Class.create();
sc_getUserData.prototype = Object.extendsObject(AbstractAjaxProcessor, {
   getData: function() {
   //gs.log('Debug>>> is in getData');
   var usrData = '';
   var usrId = this.getParameter('sysparm_sys_id');
   //gs.log('Debug>>> ' + usrId);
   var gr = new GlideRecord('sys_user');
   gr.addQuery('sys_id', usrId);
   gr.query();
   while (gr.next()) {
   usrData = gr.user_name+','+gr.email+','+gr.phone+','+gr.title+','+gr.department.getDisplayValue();
   //gs.log('Debug>>> usrData = ' + usrData);
   }
   return usrData;
   },

   type: 'sc_getUserData'
});

Create an onChange client script to go along with that.

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
   return;
   }
   //Type appropriate comment here, and begin script below
   var ga = new GlideAjax('sc_getUserData');
   ga.addParam('sysparm_name', 'getData');
   ga.addParam('sysparm_sys_id', newValue);
   ga.getXML(callBack);
}


function callBack(response) {
   var usrArr = response.responseXML.documentElement.getAttribute("answer").split(',');
   //g_form.setValue('network_logon',usrArr[0].toString());
   g_form.setValue('u_email', usrArr[1].toString());
   g_form.setValue('u_phone', usrArr[2].toString());
   g_form.setValue('u_title', usrArr[3].toString());
   g_form.setValue('u_department', usrArr[4].toString());
   alert(usrArr);
}

This seemed to work much better for me. Its important that the Script Include be Client Callable, that your client script includes the line ga.addParam('sysparm_name', 'getData'). The rest you should be able to tweak to the names of the fields you are trying to populate. Hope this helps!

I Agree, to improve performance at client side we must avoid using Glide record and get_reference() method.

GlideAjax is recommended to use at client side to fetch data from server.
