Sorry to ask questions and ask for portlet dev suggestions here, but
thought I might get a better response here than on the portlet-dev list
on the first question (since I don't think that many people have
subscribed to portlet-dev).
I was thinking about using Spring Web Flow 2 but the example (
http://static.springframework.org/spring-webflow/docs/2.0.x/reference/html/ch13s02.html
) references a class org.apache.pluto.core.PortletServlet (
http://portals.apache.org/pluto/pluto-container/apidocs/org/apache/pluto/core/PortletServlet.html
) that according to the javadoc was only added in Pluto 1.1, which is
newer than the Pluto 1.0.1 RC2 included in uPortal 2.5.3 (which we're
still using) or Pluto 1.0.1 in uPortal 2.6.1.
So to use spring mvc + webflow 2 in portlets with uPortal, we must be
using at least uPortal v3, right? (Because uPortal v3.0.2 uses Pluto
1.1.6 and uPortal 3.1.0 M1 uses Pluto 1.1.6-SNAPSHOT)
Basically, I am working on the JA-SIG MailPortlet, and I'm trying to
setup a controller for user preferences such that in the same
preferences view it shows (all at once) a list of current mail accounts
(that you can click on and it will populate the edit form in the same
view), a dropdown of a list of templates for the provider (GMail, .Mac,
MobileMe, AOL, or Custom) that you can select which would populate the
form (for a new account), and then the new account form at the bottom. I
could split that up, but I really wanted to try to contain it in a
single portlet "edit" view, which I *thought* would be simpler.
My first attempt was to have a bunch of forms in a bunch of hidden divs
(for the existing accounts and templates) but that was too messy and I
couldn't easily tie a ton of forms like that to a form-backed object via
Spring MVC very easily and only update the form that was being shown
(not without basically having to hand implement all of the get param
from request/set param on object stuff on the way out and in as well as
hand-implementing form validation.
My second attempt (still in-progress) is to have a single form to edit
the account and basically load that form based on the existing or
template account clicked on, then user edits and saves. But this is not
very clean either.
I was really hoping for something clean and easy, and was thinking
webflow 2 might be better. :) Oh well. Suggestions welcome!
Thanks in advance,
