[S2] Handling input result on a CRUD action
I have a problem I'm trying to solve when the validation fails on a crud
action. This action has add/create, edit/update, and list methods that all
get called correctly. Now when the validation fails I have a list of items
that I need loaded. Right now I have a prepareEdit and prepareAdd methods
that load this list on the initial load. However when the validation fails,
for example on an update it calls the prepareUpdate. I obviously do not
want to load the list on an update if the validation passes.
My question is, are there any good solutions to handle this? Right now I'm
thinking either to detect the input result name in the prepareUpdate or
build an interceptor to handle this. Anyone else run into this issue and
find a good solution?

I agree with Dave as well. I ended up creating one interceptor and one
interface. The interceptor registers a PreResultListener. I then just
check for Action.INPUT in the result code. If input is returned it will
call the prepareInputErrors method if it's available.
So far it works perfectly.

Just read Dave's thought. Much better.

Under default circumstances you'd lose your error messages.

Just a thought but why don't put a redirect acrtion in your result
'input' on your update action. That way if it fails it will run
prepareEdit.

Do you think I would need to check the actionErrors/fieldErrors rather then
just check for the input return value?

You could just check to see if there are any errors before running the prepare logic; this could be done in an interceptor as well "prepareWhenErrors" or something.
