Hi,

I'm setting the attribute for a regular Selection field - no grouping happens automatically - on page refresh the cards remain ungrouped.

state = fields.Selection(
    [
        ('draft', 'Unavailable'),
        ('available', 'Available'),
        ('borrowed', 'Borrowed'),
        ('lost', 'Lost'),
    ],
    'State',
    default='draft',
)

...

<kanban default_group_by="state" class="o_kanban_small_column">

Forcing the grouping via view search record and action context works fine, so as via UI by manual filter apply...

Is there anything required for the default_group_by to work?

Thanks.
