I'm creating buttons in a m2o table to open the full detail form for a record in the current window rather than a popup (with attachments and such).

I would like to have the ability to scroll through all records of the domain with the usual "<" and ">" buttons, but it only displays 1/1 if I go straight to the form.

If I switch the "views" to have 'tree' and then click on one of them it works, it will show (e.g 1/7 and allow < > to go through found records). Is there a way to have it work that way going straight to the form view?

@api.multi
def open_task(self):
    return {
        'type': 'ir.actions.act_window',
        'name': 'Open Task',
        'views': [[False, 'form'], [False, 'tree']],
        'res_model': 'project.task',
        'res_id': self.id,
        'target': 'current',
        'domain': [('site_id','=',self.site_id.id)],
    }
