getDisplayValue() not working in a catalog client script

[Matt Small1]

We are currently on Dublin patch3 and I am trying to set up a catalog client script where when a 'requested for' person is chosen I want to write some of the information from the user record to read only variables.   The problem it seems is that the getDisplayValue() for a reference field on the user record, like manager, does not seem to work.  

Here is my catalog client script -

var rq4 = g_form.getValue('requested_for');

  //   alert('The req for id is ' + rq4);

  var gr = new GlideRecord("sys_user");

  gr.addQuery("sys_id", rq4);

  gr.query();

  if (gr.next()) {

  var mgr = gr.manager.getDisplayValue();

  //alert (mgr);

  g_form.setValue('v_current_mgr', mgr);

  g_form.setReadOnly('v_current_mgr', true);

If I remove the 'getDisplayValue from the mgr variable   then the sys_id of that manager field will be displayed but I want the name. Other than doing another GlideRecord on the manager   does anyone have an idea on why this would not work?   I can use this code in a backgroup sript and I get the manager name ok.   Just wondering if anyone else has run into this issue.

Client GlideRecord object does not support getDisplayValue() function... It would only be supported when it runs on gliderecord object at server side.

So would suggest, write up a script include to return the display value of manager for the corresponding user.

you can use the below script

var rq4 = g_form.getReference('requested_for');

g_form.setValue('v_current_mgr',rq4.manager);

I suppose that your v_current_mgr variable is a reference field to sys_user table. The script which I have mentioned above is not a best practice according to service now.

The best possible way is to initiate a GlideAjax call on your client script, and plac eyour GlideRecord query into a script include.

Hi Matthew,

It is recommended to use Callback function with the getReference function.

Refer to the following Wiki Link:-
