Hi community,

I try to use on_change method (Odoo 9c) to change a field value on the same view, code as follow:

class xyz(models.Model):

   ....

    'qty' : fields.integer('Qty'),

    'buff_qty': fields.integer('Buffer Qty'),

    ....

    def on_change_qty(self, cr, uid, ids, qty, context=None):

        return {'value': {'buf_qty': qty}}

on view :

    <field name="arch" type="xml">

             <field name="qty" on_change="on_change_qty(qty)" />

The code and view loaded without error but when I changed the qty field nothing happend.  I did see a "loading' text shown up on top of the form for a while , but buf_qty don't change the value as on_change defined.

I tried the @api.onchange & remove the on_change from view , code as follow

@api.onchange('probability')

def  set_buff_qty(self):

    self.buff_qty = self.qty 

still no luck .... :(

Any thing I missed?

Thank you Community :D
