Why I just can not get the field value from UI Macro

[James100]

Hi,

I have a field ('name') and a UI Macro on a form.

The UI Macro is just to get the field value and display it. The code is like below.

-----------------

<?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_user" object="true">
        ${ref_parent}.getValue("name");
    </g:evaluate>
    
    <div>name=${jvar_user}</div>

</j>

-----------------

Below is the page I'm getting. saying there is a reference error. I'm not familiar with Jelly and have no idea what's wrong. Can you help me out?

Hi James,

try adding logs

<g:evaluate var="jvar_user" object="true">
        var value = current.name;

        gs.info('Value is: ' + value);
        value;
    </g:evaluate>
    
    <div>name=${jvar_user}</div>

Hi,

I used ${jvar_user} but it still didn't work. And there's nothing in application logs.

Are you sure this works in your instance?

Hi James,

below worked for me in my instance; you need to use <g2:evaluate> tag; phase 2 jelly tags

I believe using phase 1 jelly i.e. <g:evaluate> it doesn't get the value

<g2:evaluate var="jvar_user" object="true">
        var value = current.name;

        gs.info('Value is: ' + value);
        value;
    </g2:evaluate>
    
    <div>name=$[jvar_user]</div>

Hi James,

Here is how your script should look like.

<?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_user" object="true">
        var value = ${ref_parent}.name; 
        gs.log(""Value is "+value);
        value;
    </g:evaluate>
    
    <div>name="${jvar_user}"</div>

</j:jelly> 

If it still does not work, then go to system logs->All and check for this line

value is
