question mark in the end of url causes wrong list display in admin panel

[konstantin.pavlovsky@…]

I have customized display of list of orders with list_display.
it works fine.
there are all nessesery columns i need.
but when i put question mark (for GET method) in the end i can see only first field of my model in the list.
and it is not the default onem str it is just first field in model

here is my model

class Orders(models.Model):

manager = models.ForeignKey(User,verbose_name=_("Manager"))
ordertext = models.TextField(_("Order contents"))
order_date = models.DateTimeField(_("Order date"))
client_name = models.CharField(_("Client"),maxlength=255)
order_state = models.ForeignKey(OrderStates,verbose_name=_("Order state"))
class Admin:

list_display = ['order_date','client_name','manager','order_state']
list_filter = ['manager','order_date','order_state']
pass

class Meta:

verbose_name = _('Order')
verbose_name_plural = _('Orders')

def str(self):

return (self.client_name)

after 5 more minute surfing ive discovered that my problem appears randomly. and doesnt depend on question mark

ok.
problem was solved by restarting server.
as i understood it is nesessery to restart apache every time i make any changes.
is it a problem of mod_python only? how to avoid it ?
