They are the lowest level in the chain. Constants and submitted values override them. If you need to override submited values you have to do something special, such as setConstants when displaying the form (as long as you don't use setConstants when processing it should be fine). Or, probably a better solution, simply rewrite the values stored in QFC's data store. -- Justin Patrin
