Hiding "Add Me" UI Macro when record is inactive

[rlehmann]

We've used http://www.servicenowguru.com/system-ui/ui-macros/add-me-ui-macro-user-group-fields/ to add the "Add Me" UI macro to the Assigned to field on task table records (Incident, Problem, Change, Catalog Task, etc.) to give people a quick way of assigning the ticket to themselves.

Previously we leveraged a client script to hide the macro from the form when the record is inactive.

To align with best practice, we are trying to retire any client scripts using DOM manipulation and update the macro.

I've attempted to tweak the macro to only work when the record is active.
The challenge is that in order for this version to work, we need to include the Active field on the form itself.
Preference is not to have the Active field visible on the form.

Is there another way we can achieve this without adding Active to the form?

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
   <j:set var="jvar_n" value="add_me_${ref}"/>
   <a id="${jvar_n}" onclick="addMe('${ref}')">
     <img border="0" src="images/icons/user_obj.gifx" title="${gs.getMessage('Add me')}" alt="${gs.getMessage('Add me')}"/>
   </a>

   <g2:evaluate var="jvar_groups" expression="gs.getUser().getMyGroups()" />

   <script>
      function addMe(reference) {
         //Hide any field messages
         g_form.hideFieldMsg('assigned_to', true);

         //Check to see if the user is a member of selected group
         var aGrp = g_form.getValue('assignment_group');
         var myGroups = '$[jvar_groups]';
		 var active = g_form.getValue('active');

         if(active === 'true' $[AMP]$[AMP] aGrp $[AMP]$[AMP] myGroups.indexOf(aGrp) > -1){
            //Get the user reference field and populate the current user
            var s = reference.split('.');
            var referenceField = s[1];
            g_form.setValue(referenceField, '$[gs.getUserID()]');
         } else if(active !== 'true'){
			//Display a field error message
            g_form.showFieldMsg('assigned_to','Unable to update Assigned to. Record is no longer active.','error');
		 }
         else{
            //Display a field error message
            g_form.showFieldMsg('assigned_to','You are not a member of the current assignment group.  Please select one of your groups and try again.','error');
         }
      }
   </script>
</j:jelly>

Thanks in advance.

@rlehmann May I know how you’re making fields read-only? Are you using UI policies or client scripts?

[rlehmann]

Ui policy.

[Sai Kumar B]

@rlehmann Can you try ACL to restrict write access on Assigned to field for inactive records and see if UI macros are still accessible or not?

[rlehmann]

ACL already exists.

I did try disabling the UI policy and set the condition of the ACL to active is true.
No change in the visibility of the UI macro.

In script tag you call the client callable script include using GlideAjax and pass the sys id of the record.

In script include you write the code to get the value of active field.

Now in the GlideAjax callback function you have the active field value. Use it to add your logic to hide the ui macro.

Please mark as correct answer if this solves your issue.
