Advice on Handling From Validation
Hi,
I have the following scenario running with an application:
1. A setup action gets called and a form bean gets created, some
lists in the form bean are populated with collections and then the
whole mess gets sent to the user.
2. The user fills out the form and clicks save.
3. A save action gets called but before that, validation happens (the
form bean extends ValidatorForm) and finds the user forgot to enter a
title. The user is forwarded to the form jsp to correct the error but
the collections are no longer available.
4. Huge error ensues, user is mad, money is lost.
After doing some research it seems that I have a couple of options:
1. When validation fails, return the user to an action instead of
directly to the jsp. Said action can repopulate the list and things
are good to go.
2. Session scope the form bean.
3. Use AJAX to populate the collections on the form and forgetaboutit.
Are there best practices for this sort of thing? Am I missing
anything else?
Thanks in advance for your help.
Cheers,
Jon

Yup. That's pretty much the case. I like the validation framework and
have been using it for a while. I run into these cases where I need
to repopulate collections within the form.
Javascript is a good alternative for sure, especially given JQuery
and other libraries which make it easy to do that. I'll probably go
that path for now.
Thanks,
Jon

Why not use JavaScript for preliminary validation of the form?
Sounds like your main issue is a user not entering a value in a field.
