The values are populated when you instantiate the form initially like so:

$form = new sfForm($initialValues);

and when you do:

$form->bind($tainedValues);

Check out the generated form classes. You will see methods like
updateDefaultsFromObject(), saveRelationNameList(), etc. All other values
are updated to the object in the sfFormDoctrine::updateObject() method where
we simply use the Doctrine_Record::fromArray() method.
