Maybe some issue with getReference?
Best practice is to use GlideAjax and that works for me at least. I'll provice some sample code you can modify to your needs
Catalog Client Script (onChange)
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
//AJAX call to lookup Requested for information
var ga = new GlideAjax('demoUtils'); //Name of Script Include
ga.addParam('sysparm_name','requestedForValues'); //Function in Script Include
ga.addParam('sysparm_requestedFor', newValue); //Parameter to pass to function
ga.getXML(setData);
}
function setData(response) {
var answer = JSON.parse(response.responseXML.documentElement.getAttribute("answer"));
if (answer){
g_form.setValue('demo_user_id', answer.rf_uid);
g_form.setValue('demo_mobile_phone', answer.rf_mPhone);
}
}
Script Include
var demoUtils = Class.create();
demoUtils .prototype = Object.extendsObject(AbstractAjaxProcessor, {
requestedForValues: function() {
var rf = this.getParameter('sysparm_requestedFor');
//Get the User Record for Requested For
var gr = new GlideRecord('sys_user');
gr.get(rf);
//Create an object with parameters
var obj = {};
obj.rf_uid = gr.getValue('user_name');
obj.rf_mPhone = gr.getValue('mobile_phone');
return JSON.stringify(obj);
},
type: 'demoUtils '
});
