Hi,

i tried to create an object from an onchange-method. The problem is, that i get following error, after creating the object:

Traceback (most recent call last):
  File "/home/odoo/odoo/openerp/http.py", line 500, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)
  File "/home/odoo/odoo/openerp/http.py", line 517, in dispatch

    record._onchange_eval(name, field_onchange[name], result)
  File "/home/odoo/odoo/openerp/models.py", line 5648, in _onchange_eval
    params = eval("[%s]" % params, global_vars, field_vars)
  File "/home/odoo/odoo/openerp/tools/safe_eval.py", line 313, in safe_eval
    return eval(c, globals_dict, locals_dict)
  File "", line 1, in <module>
ValueError: "name 'parent_id' is not defined" while evaluating
'[use_parent_address, parent_id]'

Here is the code line which provide the object creation:

vals = {
'list_id':list_id,
'email':email,
'partner_id':partner_id,
'name': name,
}
self.pool['mail.mass_mailing.contact'].create(cr, uid, vals, context=context)

Can someone give me a hint how to fix that?
