Hi.
I'm trying without success order and group by a tree view.
I defined action window with this context:
context="{'order_by':'start_datetime desc', 'group_by':'start_datetime:day'}"
I get a grouped tree view by day but not with the inverse order.
Can't group and order fields on and unfiltered view pressing header column buttons and grouping.
¿Posible bug in data.js?
