I was thinking that I had to do it through validation. Like:
validate input against class function
spit out scenario
follow-on action triggers call to DAL with a look-up function
trigger output view that takes ID from row in the table and passes
relevant data to the view
but so far I can't figure it out. looks like something to do with
crud.settings.create_onvalidation:StorageList() for the validation
part. am I on the right track there?
