Oh, right, no... The browser doesn't see the new URL (and hence the anchor)
with a forward. It'd work if you configured struts to redirect to the input
view instead of forwarding, but then you have the same caveats about preserving
state across the redirect...

Oh, and Laurie, just so you know, putting an anchor on a mappings input JSP

Thanks for your comments everybody.... I fiiiiiinally found the answer :)
I'm still using the DynaValidatorForm, and basically just had to do what
Laurie recommended in her 2nd point.
I just need to check for messages on the JSP page using the
messagesPresent logic tag... ie:
<logic:messagesPresent>
<script>
setTimeout('self.scrollBy(0,500)', 300);
</script>
</logic:messagesPresent>
Using "document.location" would cause an infinite loop, so I basically
needed to scroll down the page using a timeout.
*Phew... Struts has so many crazy tags, I learn new ones every day :D
Thank to all that helped, and let me know if you have any
suggestions/questions.
Thanks !

I'm not sure if you can tell the browser to scroll to an anchor from
within the page (rather than in the URL). It would have to be done using
Javascript, HTML doesn't provide this.
Other than Javascript, I can think of two possibilities:
1) in your JSP, check for errors and, if they exist, render a
browser-side redirect as the response where the redirect is to the same URL
but with the anchor appended. You'd have to put any data the page needed
into session scope (or append it to the redirect URL) to maintain it across
the redirect, though.
2) if the input to the validating action is a path to a JSP (as opposed
to a Tile name or action), you can add the anchor there. I.e. in
struts-config.xml for your action, you'd include
input="/path/to/page.jsp#anchor"
That way, if validation fails, it'll forward to the 'input' path which
includes the anchor you need to target.
HTH,

Thanks Wendy !
The problem I'm running into is that since I'm using a
DynaValidationForm,
and errors are found, I'm never even reaching my Action... so, the
setting
of the anchor in the request wouldn't work.
I would somehow need to determine if there "were" errors on the JSP
page
itself (like the struts tag "html:errors" does)... and then apply the
necessary logic.
Any ideas ? Thanks !

When validation finds that there are errors, and returns to the form
page
with displayed errors... I want to anchor to the lower part of the
large
form page... so, only the errors and the form shows... not the text
above.
Anybody have any ideas on how to do this !?
I've tried about 100 different hacks, with no luck.
The problem is that when the page is rendered (when the links and
form's
action are determined) you can't _know_ whether or not there will be
errors.
It hasn't been submitted yet... the user hasn't even seen it.
See if this helps:

You'd probably want to test for the presence of errors, and skip
setting
the
request attribute.
