GlideAjax returning null from Script Include

[NishmithaS]

I'm trying to convert List Collector sys_ids to user names using GlideAjax. The List Collector returns comma-separated sys_ids, which I pass to a client-callable Script Include. However, the GlideAjax response is always null.

Script include 

var getwatchlistusernames = Class.create();
getwatchlistusernames.prototype = Object.extendsObject(AbstractAjaxProcessor, {

getName: function() {
var ids = this.getParameter('sysparm_ids');
var names = [];

var gr = new GlideRecord('sys_user');
gr.addQuery('sys_id', 'IN', ids);
gr.query();

while (gr.next()) {
names.push(gr.getValue('name'));
}

return names.join(',');
},

type: 'getwatchlistusernames'
});

Catalog Client script 

var ga = new GlideAjax('getwatchlistusernames');

ga.addParam('sysparm_name', 'getName');

ga.addParam('sysparm_ids', g_form.getValue('user'));

ga.getXMLAnswer(callback);

function callback(response) {

    alert(response);

    // g_form.setValue('short_description', response);

}

plz try debugging your script that everything working fine..

var getwatchlistusernames = Class.create();
getwatchlistusernames.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getName: function() {
        var ids = this.getParameter('sysparm_ids');
        gs.info('sysparm_ids received: ' + ids);

        if (!ids) {
            gs.info('ids param is null/empty');
            return '';
        }

        var names = [];
        var gr = new GlideRecord('sys_user');
        gr.addQuery('sys_id', 'IN', ids);
        gr.query();
        while (gr.next()) {
            names.push(gr.getValue('name'));
        }

        gs.info('names found: ' + names.join(','));
        return names.join(',');
    },
    type: 'getwatchlistusernames'
});

also in client script :

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') return;

    gs.log('newValue (List Collector):', newValue);

    var ga = new GlideAjax('getwatchlistusernames');
    ga.addParam('sysparm_name', 'getName');
    ga.addParam('sysparm_ids', newValue);
    ga.getXMLAnswer(callback);

    function callback(response) {
        var status = response.responseXML ? 'XML received' : 'NO XML';
        gs.log('response status:', status);

        if (response.responseXML) {
            var answer = response;
            gs.log('answer value:', answer);
            alert(answer);
        } else {
            gs.log('full response object:', response);
        }
    }
}

If my response helped mark as helpful and accept the solution.

Hi @yashkamde 

Thanks for your reply.

I already checked the Client callable checkbox. It is checked.

The Script Include name and function name are the same.

Both the Script Include and Client Script are in the Global scope, but it is still returning null.

Things to check

1) is your script include client callable

2) if script include & client script are in different scopes then is your script include accessible from all scopes? Did you invoke script include with complete API name

screenshots please
