How can I add an advanced reference qualifier in a UI Page Jelly script?

[Suvitha Murugan]

Hi,

I tried adding an advanced reference qualifier on a UI Page, but it’s not working as expected. I want to display the values dynamically based on the current record. Could someone help me resolve this issue?
Thanks in advance
Script:

<?xml version="1.0" encoding="utf-8" ?>

<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

    <g:evaluate var="jvar_sys_id" expression="RP.getParameterValue('sysparm_sys_id');" />

    <input type="hidden" id="record_sys_id" value="${jvar_sys_id}" />

    <style>

        label {

            font-weight: bold;

            margin-bottom: 5px;

            display: block;

        }

    </style>

    <g:ui_form>

        <table border="0" width="100%">

            <tr>

                <td style="width:10%">

                    <label for="Business XXX">Business  XXX</label>

                </td>

                <td style="width:25%">

                    <g:ui_reference name="user" id="user" table="xxxxxx" query="new x_Utils().getXXXXUsers('${jvar_sys_id}')" />

                </td>

            </tr>

            <tr>

                <td colspan="2" style="text-align:right;padding-top:10px;"> <button class="btn btn-default" onclick="closeWindow()" style="margin-right:10px;">Cancel</button> <button class="btn btn-primary" onclick="update_button()">Submit</button> </td>

            </tr>

        </table>

    </g:ui_form>

</j:jelly>
