In V11 CE, I have the Google Spreadsheet module installed and connected to my database.  The oe_browse function works fine and pulls data into the spreadsheet so I know the connection is fine and everything is configured properly.

However, when I enter a related field in the list of columns to fetch, such as 'lines.product_id.list_price' (fetching from the 'pos.order' model), the cell displays 'Undefine', even though I know that there is definitely data in that field in the database.  I know this because I have checked by exporting the pos.order in csv including the related field above.

Is this a limitation of the Google Spreadsheet module/script or is there something not working properly in the background?
