Upgrade safe subpanel customization

I am trying to create a new subpanel but my changes do not seem to take effect.

I would like to add a subpanel for tasks on the contracts module. The relationship already exists but I cannot get the subpanel to show up.

I dug around in the files and I found the ‘modules/AOS_Contracts/metadata/subpanelsdef.php’ and that corresponds with the subpanels that are currently visable. I have made a copy of this file and placed it in ‘custom/modules/AOS_Contracts/metadata’ and edited it to add the tasks subpanel using the default ‘aos_contracts_tasks’ relationship and then did a quick repair but my modifications are not showing up.

This is my ‘custom/modules/AOS_Contracts/metadata/subpanelsdef.php’ file:

<?php
if(!defined('sugarEntry') || !sugarEntry) die('Not A Valid Entry Point');

Is there something I need to do to get my customizations to show up after placing in the custom directory? I have checked it is owned by the correct user and permissions set to 755.

Hi having the same issue here. Did you locate a solution?
