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 ?
