Hi, I'm trying to fix a behavior in a custom modules we have developed [1] [2]. We added a field on sale_line model in order to store the cost_price of the product to compute the margin of benefit. This field is filled automaticaly each time product changes. The form view of the sale (pos sale) has a tree view of sale_lines that allows enter lines without the need of changing to form view (editable). I think here is the problem. Almost always it works fine except in one case: the firts time you open the view of the sale, you enter a product and its quantity and push enter instead of tab. In this case, and only in this case, the field cost_price is not filled automaticaly.
Could someone orient me where to find the issue, please? Thank you. [1] https://bitbucket.org/zikzakmedia/trytond-sale_pos [2] https://bitbucket.org/zikzakmedia/trytond-sale_margin
