Recovering from form validation errors
I am validating fields in my ActionForm using the validate() method. Upon finding errors, I return a populated ActionErrors object. When the thread of control is passed back to the input JSP, a List of users used to populate an html:select is no longer in the request object (since this is a new request at this point). Since I never get to my Action class, I don't get the List populated.
I really don't want to put the List of users on the session if I can avoid it, since the List really should be re-built with each request.
Is there a "best-practices" way to deal with this problem?
Thanks

Thanks for the reply. I had just moved my validation code out of the Action
to clean it up a bit. I hadn't thought of calling validate() from the
action, though.

set validate="false" in struts-config and do that validation in your
action instead. You can still call the validate method on the form,
of course, and then you have the opportunity to repopulate the
request with that list.
There's no other work around that I'm aware of. Your situation
falls outside of what the pre-action validation is supposed to handle.
