HI ,
Thanks for your reply. But How do I implement this in my current scenario.
displaying records on the screen using a list from session and not using form
variables.
if I use 'indexed="true"' on html:chekbox how do I capture the change?
i.e.
HTML generated will look like as below.
<input type="checkbox" name=list[0].varname value="on" ...
I have 'n' records to display on a page. If I check some records and uncheck some
previously checked records and submit the page. How do I capture this change in my
action class? so that next screen will pick up checked records change.
Your help will be really appreciated.
Take Care,
Jignesh

You don't want to use multibox ... you need to set 'indexed="true"' on
the html:checkbox control in the logic:iterate or c:forEach loop that
displays your list.
