Hi All,
I was trying to override one of Odoo's exception classes in my custom module. Here is what i tried.

exception.py
     

from odoo.exceptions import ValidationError, except_orm
from odoo.http import request
print('-------am here-------------')
class ValidationError(ValidationError):
	​def __init__(self, msg):
	​	​print('print ValidationError------',msg)
	​	​super(ValidationError, self).__init__(msg)

But still, the validation error gets called from the base class, not my custom class.
