Rather than answer you here, I've set up a wiki page showing three different options for "lazy list" type behaviour
http://wiki.apache.org/struts/StrutsCatalogLazyList I understand you wanting to only use "released" stuff - actually if you look at LazyValidatorForm, theres not much too it - most of what it uses is either already in Struts (it extends BeanValidatorForm) and Commons BeanUtils (LazyDynaBean) - creating your own lazy ActionForm wouldn't take much. In fact you can even use a LazyDynaBean directly in the struts-config.xml as your ActionForm in Struts 1.2.4 Niall ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, September 30, 2004 6:54 PM Subject: Re: How to handle multiploe unknown form fields > 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?
