Thanks for the answer! Does the resultType="chain" approach preserve the
fieldErrors and the values the user has already typed into the form? Also,
how do you prevent the edit action from retrieving the entity from the
database in the case the validation fails?
I also thought about putting the lists into the http session instead of the
request, but I don't really like cluttering the session with such things.
