Disable sorting on sale order tree view [odoo9.0c]
In sale order tree view, it will load orders with sorting function.
But When I search many orders in search box with order numbers, the last searched order didn't show at the bottom or top because sorting function in order tree view.
So How to disable the sorting function, just load the order list as the order number i searching.
i searched orders with numbers are ： 1420,1430,1440,1335,1433.
but the result order sorted are : 1430,1420,1440,1433,1355.
So is it possible that the tree view result is 1420,1430,1440,1335,1433 ?
I have tried
tree string="Sales Orders" editable="top" default_order=""
But it doesn't work. Can anybody help me ? Thank you.
