I'm using Ubercart in a D7 site. In one content type, I have an entityreference field using a views entityref to lookup products by SKU. However, when I select a product and save the node, then edit the same node, the product title shows in the entityref field instead of SKU.
In Views, the entityreference is set as follows...
Format: Entity Reference list - with only Product: SKU selected in search settings.
Show: Inline fields (the only radio button available) - again with only Product: SKU selected.
In the "Fields" section, only Product: SKU is being output; all other fields (including title) are set to "Exclude from display".
I'm not sure what other settings are important for this issue. Any help would be greatly appreciated.
