I would like to create or edit a product bill of material from sales order line. I have Quotation and Sales Order configured to open product properties on orderlines. I created a windows action button to open BOM form from this popup. but when I use the active_id in the context as is done in the button on the product form it passed the ID of the sales order. I can not seem to find the correct way to pass the current product id from the sales order line.
