hi, I want to show "historical" sales order lines for the customer when user is creating a new sale order, so I've created a fields.function (type='one2many') in sale.order.

Everything works fine, in sale order form view I have a tree for "historical" lines for this customer.

But when creating a new order, historical lines are not refreshed until order is saved. I would like to refresh lines just after partner_id is set. How can I "recompute" functional fields inside a onchange event? I think store parm in fields.function is only for triggering events when data "in other" objetcs change, not for self...
