Hello,

I have this field :

switch_power = fields.Selection([('1','On'),('0','Off')],'Power')

And i have defined a button which change the value of "switch_power" according to this function :

@api.multi
def message_test(self):

    if(self.switch_power=='1'):
        self.switch_power='0'
        raise osv.except_osv(('Button test!'), ('Le button est on'))

    else:
        self.switch_power='1' 
        raise osv.except_osv(('Button test!'), ('Le button est off'))

The problem is when i click in the button, The message is displayed, but the value of "switch_power" dosen't changed.

Any help please ?
