populate_list - Relationship

Question

Hi all. 
 I'm looking to simply use populate_list to pull a relationship from Leads into Opportunities. I've created what I thought was the correct simple file of: 
 <?php
$dictionary["Lead"]["fields"]["opportunity"]['populate_list'] = [
 'contacts_leads_1_name' => 'contacts_opportunities_1_name',
]; 
 However this has failed to work, I've put this file here - custom/Extension/modules/Leads/Ext/Vardefs 
 
 Simply it should pull the Contact through to the Opp in the custom relationship. Have I missed anything obvious? 
 Thanks, 
 Daniel

populate_list works only on: 
 
 creating child record from subpanel under parent module: populate_list must be placed in the field 'link' of the parent module which relates to child module. 
 creating child record directaly from create view and choose parent record in the respective relate field: populate_list must be placed in the field 'link_name' of the child module which relates to a parent module. 
 
 According to your code, it seems you are trying to create an Opportunity from subpanel under Leads. Is that the real scenario? 
 Anyway, you are missing the field 'link_id' in the populate_list definition. 
 
 Additional tip: populate_list doesn't work on selecting from existing records.
