No suggestions in Data Selector (Rules) following this guide to display alternative prices for certain roles: http://jamestombs.co.uk/2012-09-14/drupal-commerce-different-prices-different-customer-groups

But for some reason I don't get any suggestions or dropdown in the Data Selector field.

I've tried changing jquery versions which doesn't correct the error.

Any other ideas? I've added a detailed description of my approach below the screenshot.

It's a d7 commerce site, all modules is the latest versions



Step by step approach to making the pricing rule


created 'retailer' role 
added a new field of the type 'price' called field_ppd (ppd = price per dealer)
created a 'retail price' rule at admin/commerce/config/product-pricing/rules/add
added a 'Entity has field' condition
And it's in the condition config I'm stuck since the Data Selector field doesn't auto-suggest when I start typing
It is a bug in the rules module. The issue is discussed HERE.
You can either apply the patch in the issue or use the latest dev version of the jquery update module which allows you to select the drupal default version of jquery for the backend.
