One2Many ordering arrow wrongly stays after save
When you save or reload a record with one2many field, the sort order is lost.
Reproduce:
Open a record with several lines in a one2many field, for example a shipment.
Sort the lines by clicking on the head of a column. than click save or reload. The lins are in their original order (by id i suppose) again.
The client remembers the prefered order, as the little arrow in the head of the column stays, but the lines ar not sorted any more, so to restore my order i have to click 3 times at the column again.
by the way: in the mail list view were all the records of a model are listed, this works fine.
