I have a product attribute that I populate from my own custom table, I have a class that extends from
\Magento\Eav\Model\Entity\Attribute\Source\AbstractSource to be able to populate my attribute using the source property.
This works well for a select input but I need it to work with a Visual Swatch using a field in my custom table as the location for the Swatch image.
This seems impossible to do, any idea on how I can achieve this is very much welcome.
Thanks for any help.
