I'm a little confused about what you're actually trying to achieve but
in your situation it's probably simplest to use a sfValidatorCallback.
Which will allow you to run you own custom logic.
http://www.symfony-project.org/forms/1_2/en/B-Validators#chapter_b_sub_sfvalidatorcallback
There you can check if the value has changed - and if so - to check
against Doctrine if the new field is valid.
