I understand the JSP side of this eqation as you wrote it, although I should have said I was looking for a solution that doesn't use Struts taglibs because I try to avoid them at all costs, but that aside...
I'm still unclear however on what the ActionForm does... Using this concept, do I HAVE to use the LazyActionForm you wrote? I'd prefer to only use things that are built-in to Struts, and unless I'm missing it in the docs, that's not. The question I'm getting at is that, like I said, the JSP code you wrote makes sense, but what will put the submitted parameters into the collection in the ActionForm when the submission happens? That's the part I don't see. Thanks for your help! -- Frank W.
