How can I use <html:multibox /> or <html:checkbox /> with values that are
stored in the request or page context?. I would like to do something like
<html:multibox value="<%= request.getAttribute (\"value\") %>"/> without
using the <% %> tags. Is there a way to use the JSTL Expression
Language or
tell the <html:multibox /> tag to get the value from an attributo?.
You can... but the typical way to handle this is to put those values
into your form bean. Do this in the Action, then forward to the JSP and
let the framework render the correct values in the HTML form elements.
If you use the 'value' attribute directly in the tags, you lose the
ability to re-display the user's incorrect input if the form fails
validation.
LOL, I just knew if I didn't say something to that effect you'd jump in
Wendy ;-) Sorry, I should have mentioned the (non-obvious) reason I didn't:
in the specific case where you're populating the 'value' attribute from a
request parameter, you don't loose anything. The user's input *is* what
you're redisplaying.
The caveat with that is, of course, if you redirect back to the original
page (rather than forwarding, as by default) you'd loose the request data.
Storing it into a form bean, and putting that bean in session scope, is the
solution in that case.
