If you are using indexed properties, you just name the field one name, e.g. productId, and the indexing gives the field unique names when in a list, e.g. productId[0], productId[1] etc. Similarly with units[0], units[1]

Currently, we are a stateless application. So on each request we will read the database and get a list of products.
Then our JSP will generate a from a list of products. Each product will have an input that can accept the
number of units per product.
The problem I have is that each input field needs a different name. How can I map these different names back to a list on a ActionForm?
Also, I don't really see how DynaForm helps this problem.

Yes you can have indexed properties & dynaforms. I---------------------------------------------------------------------
do not use them, I prefer nested properties. But I think the docs are
quite good on this topic.
Re: your problem, I was just asking about categories
because I have no concept of how your database stores your products.
Looking at your database should give you ideas how to design the
data model in your business & view layers.
Do you store / 'persist' your products somehow? Or
do they only last as long as the user's session? Do you use a database?

All we have is a product ID. There is no

How do you think category could help?
Also, have you used an indexed property and
DynaForm?

Still it depends. How does the database handle the
new products? Can you at least categorise them?

myself in the Action. Do you agree?

Hi Cornellious, it depends whether you know beforehand what the
full
set of possible fields could be, or whether the fields
themselves
are not limited in name or type.
If the former, then it would be easy to make a
form
that defined them all, and to use logic tags to display the needed
fields or not in JSP.

I am wondering what is the best approach to

I have a JSP page that will display quantity

how many products will be in the list until
runtime.
How can I set up my ActionForm to handle the
list
in
input parameters?
Thanks for any help.
