Jacky,
Recently an associated of mine became tired of trying to get DHTML to work properly
between NS and IE and came up with a crafty way of hitting the server just to pass a
flag value in a request parameter to tell the JSP to add a new section of HTML to the
page without affecting any other data that had already been entered on the page. The
Action class basically did nothing but route the request to the same JSP page.
He used a single form per page and named the line item input field(s) with "[counter]"
and the Form class set accessor method was something like setX(String key, String
value) { x.put(key,value); } where x is a HashMap. Both the JSP and Action class that
processes the data use a loop to pull data out of the HashMap where key = "1", "2",
"3" etc. until a null value is returned.
Although this is a bit creative and worked, I am not sure if it is recommend by the
Struts old-timers.
I would avoid using multiple Forms per page. I would also avoid any use of the
innerHTML for dynamic client side adding of input fields into a Form. About the only
choice left that I see is to make a server hit and let the JSP build more line items.
Anyone else out there use something like a "NoAction" action for this sort of thing?
I hope this helps?

I have a jsp that contains 4 forms. One for main info, another for
merchandise info, and two for ship address address and bill address.
Currently upon submit, I have an addressAction that gets passed the
addressForms info. I stuff those parameters into AddressValue objects and put
them into the httpRequestServletAttribute. I do the same with
lineItems (which I need to change in the future because I need to have the
ability to have muliple lineItems). Then the createPoAction gets the
address and lineItem value objects from the requestAttributes and then call
createPO(). How do I write the jsp appropriatly? Do I need to use
form nesting? On the flip side, when I retrieve from the db, can I use
this same grouping of forms or should I create a new form to diplay all
of the data? Anyone have a suggestion on how to allow for a "add line
Item" button that will just give another row of blank fields to the
existing form?
I know this a lot but am in the trenches solo!!!!!!!
