thanks paul, but i'll keep asking the database. i only thought this wouldn't be possible (to perform an action
after validation failes) - it is, of course, possible to specifiy an action as input for another action.
thanks for your time
regards art

You need to remember the values for your dropdowns between requests if you don't want to keep asking the database. There are two places you could store this - in session or in application scope. You need to decide which is more appropriate.
HTH,

i've ran into an problem using struts or, maybe, it's me not understanding the mvc concept correctly:
the user has to fill out a form which contains several drop-down-boxes filled with possible values from
a database. so i need an preceding action to gather the data from the database. if the form is submitted
it's submitted to a different action which should persist the user's inputs. however, if the user enters
semantically incorrect data he should be redirected back to the input page - loosing the data collected
from the database in the previous action.
i suppose there is no way solving this issue using form validation via the validate() method of the actionform.
another possible way would be that the second action validates the form (which would render the validate
method of the action form useless in most cases) and, if the validation fails, gathers the database records
again and forwards it to the input page. so i'd have to actions doing virtually the same.
the third way i figured out is to not use pre-populated input pages at all. i could use javascript popups to
populate certain fields. but i don't want to use popups.
i'm pretty sure that this is not a uncommon issue and hopefully someone figured out a clever way to deal
with this problem.
thanks in advance art
