can't translate on_change warning message

[Paulius Sladkevičius @ hbee]

I found that e.g. in the stock module onchange_lot_id function warning message translation don't work. If you translate this entry, in the warning will show English one, not translated.

same here (openacademy training):

    def onchange_remaining_seats(self, cr, uid, ids, seats, attendee_ids):
        res = {
            'value':{
                'remaining_seats_percent': self._get_remaining_seats_percent(seats, attendee_ids)
            }
        }
        if seats < 0:
            res['warning'] = {
                'title': _('Warning'),
                'message': _('You cannot have negative seats'),
            }
        return res

This is not translated, although the exported PO file is translated correctly in the meantime.

I'm marking this bug as not a duplicate anymore.
The messages can't be translated because the server does not pass a context parameter to the on_change functions.
It was refused to change this in v6.0 and v6.1.
But the roadmap for v7.0 states that the context will be implicitly passed everywhere.
So I'm confirming this bug for the R&D team to make sure we can eventually translate messages in on_change functions.

Marking as duplicate of #900861 because another generic solution was proposed there.
