Description
To reproduct:
1. Navigate to the product page
2. Click the lookup popup window icon for the productId field in the Search Products section on the left side of the screen
3. Search for WG-9943 and click the "Variants" button
4. Select some features and then click "Search" (there are two search buttons for some reason)
This error occurs when trying to filter the list of virtual product feature variants in the lookup popup window:
