help using validate inside ActionForm
Hi all,
In my application, I'm using one ActionForm Bean for
several pages. How do I properly use validate method
when user goes from one page to another? It's a
collection of data, so, on page 1, I need to validate
X fields, on page 2, validate Y fields, etc.
Is there an easy way to tell what page I am coming
from?
Any help is appreciated!
Thanks,
Penny

In terms of this particular requirement, what the validator framework
does is provide the concept of 'pages' and page-specific validatons
(think of a wizard, where each screen in the wizard is a 'page' and each
validation rule is marked as being applicable to a specific page).
Even if you don't want to switch to using the validator framework, you
may want to implement the same concept in your own validation logic.

While the "if" loops in the validate function of the form will work... i
somehow think you are coupling the workflow with the validation rules. Why
dont you look at the validation framework so that you "externalize" your
validation logic into xml files?
You can perform validation on a per form basis and also on a per action
basis in the validator framework. The second case may be useful to you.

A few ideas that may get you started:
you can use different names for the submit or image tags that you are
using to submit the forms, and set up an if, else if structure in your
validate method to see which page has submitted to the actionForm based
on the parameters input. or use hidden tags to do the same thing. or use
the HttpServletRequest's getPathInfo().
