Usually complex forms have limited users anyhow so I scope to session. However folks on the list have used lazy list which apparently works although i've never seen it down without two days worth of postings (I guess some folks have time on their hands). For some reason storing forms in sessions isn't a very trendy thing to do.
Search the archived for lazy list if this takes your interest, although IMO session is fine and are there to be used.

I'm having trouble (re)populating a Form with nested beans when i submit the
values with the scope set to request. If i run the exact same code using a
session scope then it works fine. Has anyone run into similar problems ? If
so, what possible causes of the problem should i be looking at ?
My actionform contains a list and a string:
private String action = ""; private ArrayList problematicOddsList = new ArrayList();
The html code generated html looks like this:
<form name="UnknownSportForm" method="post"
action="/ManageUnknownSportsAction.do">
<input type="hidden" name="action" value="update">
<input type="hidden" name="problematicOddsList[0].siteId" value="0">
<input type="hidden" name="problematicOddsList[0].sportType"
value="blahblah">
<input type="hidden" name="problematicOddsList[1].siteId" value="0">
<input type="hidden" name="problematicOddsList[1].sportType"
value="blahblah2">
Since the very same code works when I use a session scope I can't quite
figure out what i'm doing wrong. It seems to me that somehow the instance
that Struts tries to populate using the request contains a List which is
initialized to too small a size to fit the submitted data, I don't
understand why though and I'm quite sure I've used similar constructs in the
past without problems (albeit on a Weblogic server and not JBoss). Any clues
anyone ?
