Hi!

I have updated my app to rails 2.3. I have form that has few nested  
models and I am happy that I can just write  
accepts\_nested\_attributes\_for :tasks, :allow\_destroy =\> true, but  
update\_attributes! does not update my nested model. I have tried  
update\_attributes, and it works. Any ideas?

Few lines from log:

update\_attributes:

SQL (0.1ms) BEGIN  
Education Update (0.3ms) UPDATE `educations` SET `institution` =  
‘ins’, `updated_at` = ‘2009-02-03 13:34:08’ WHERE `id` = 4  
SQL (0.4ms) COMMIT

update\_attributes!:  
SQL (0.1ms) BEGIN  
SQL (0.1ms) COMMIT
