Read the tutorials and you'll get a better idea of how to do this. Make sure that you have the reset method changing all your checkboxes to false. That's a key piece most people miss. As with every other field in a struts form, you don't have to do anything, except as I mentioned above. If you aren't using a form, then the browser only sends those boxes that are checked (iirc). Which means all kinds of fun will ensue. > > Thanks, > Jignesh > > [EMAIL PROTECTED] wrote: > > > Jignesh, > > I think your problem is not related to checkbox or multibox > but to maintain a > list of modified records.
