Unable to fetch and set reference value using jelly

Streamline Cam · ‎03-06-2025

Hi! I am trying to take a field value from the form and use this to populate a field on a UI page with that value.

But it is not setting/getting the value. If i make my tags $[] I get a black reference value but if I use ${} I get no reference at all, I want to take the value from the record that is already populated.

<g2:evaluate var="jvar_cmdb_id" jelly="true">
        var val = current.getValue('cmdb_ci');
        val;
</g2:evaluate>

<g:ui_reference label="configuration_item" name="configuration_item" table="cmdb_ci" field="name" value="$[jvar_cmdb_id]" displayvalue="Testing" />

@Streamline Cam

since you are in scoped app try this

<g:evaluate var="jvar_ci_sys_id" expression="RP.getWindowProperties().sysparm_ci_sys_id" />
                    <g:evaluate var="jvar_ci_display" expression="RP.getWindowProperties().sysparm_ci_display" />

Hi @Streamline Cam -

can you please try below and if it works -

<g2:evaluate var="jvar_cmdb_id" jelly="true">
    var gr = new GlideRecord('cmdb_ci');
    if (current.cmdb_ci) {
        gr.get(current.cmdb_ci);
        jvar_cmdb_id = gr.getDisplayValue(); // Get the display name instead of sys_id
    } else {
        jvar_cmdb_id = "";
    }
</g2:evaluate>

<g:ui_reference 
    label="Configuration Item" 
    name="configuration_item" 
    table="cmdb_ci" 
    field="name" 
    value="${jvar_cmdb_id}" 
    displayvalue="${jvar_cmdb_id}" />

Hope this helps

Mark the answer correct if this helps you

Thanks for taking a look Tushar!

Sadly with that code I get nothing shown in my ui button ui page:

value="${jvar_cmdb_id}"

<g:ui_reference label="Configuration Item" name="configuration_item" table="cmdb_ci" field="name" value="${jvar_cmdb_id}" displayvalue="${jvar_cmdb_id}" />

If I change the value variable to look like this, I see the reference i icon but it's not the correct value:

value="$[jvar_cmdb_id]"

<g:ui_reference label="Configuration Item" name="configuration_item" table="cmdb_ci" field="name" value="$[jvar_cmdb_id]" displayvalue="${jvar_cmdb_id}" />

@Streamline Cam

do this for getting sysId and then another evaluate tag for display value

<g:evaluate var="jvar_sysid" object="true">
var sysId = current.getValue('cmdb_ci');
sysId;
</g:evaluate>


<g:evaluate var="jvar_displayvalue" object="true">
var sysId = current.getDisplayValue('cmdb_ci');
sysId;
</g:evaluate>

<g:ui_reference label="Configuration Item" name="configuration_item" table="cmdb_ci" field="name" value="${jvar_sysid}" displayvalue="${jvar_displayvalue}" />

@Streamline Cam

how are you calling the UI page?

You can use this logic to set the reference field in UI page, pass the display value as well

Recently I shared working solution for this

UI action popup reference value is coming as NULL

Send the sysId and display value as well and set both

function showModal() {
    var gm = new GlideDialogWindow('showchangerequest');
    gm.setTitle('My UI page');
	gm.setSize(600,600); //Set the dialog size

    gm.setPreference('sysparm_changesysid', g_form.getValue('caused_by'));
	gm.setPreference('sysparm_changenumber', g_form.getDisplayBox('caused_by').value);
    gm.render();
}

Please enhance from your side.

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
<html>
    <g:ui_form> 
        <g:evaluate var="jvar_changeSysId" expression="RP.getWindowProperties().get('sysparm_changesysid')" />
		<g:evaluate var="jvar_changenumber" expression="RP.getWindowProperties().get('sysparm_changenumber')" />
        <input type="hidden" id="changerequest1" name="changerequest1" value="${jvar_changeSysId}"></input>
        <div id='mydiv3'>
            <label id='label3'>Change Request</label>
			
			<g:ui_reference name="changerequest" id="changerequest" table="change_request" value="${jvar_changeSysId}" displayValue="${jvar_changenumber}" style="width:180px"/>

        </div>
    </g:ui_form>
</html>
</j:jelly>
