Re: Dynamic form fields on ActionForm

[Mark Lowe]

Indexed form property is what you want.. I'll avoid any clever 
explanations, grandiose meta language or to try and sell you a book.. 
And give you an example..

<form-bean name="productForm">
<form-property name="product" type="java.util.ArrayList" />
..

<action name="productForm" path="/products" scope="session"...
...
DynaActionForm theForm = (DynaActionForm) form;

ArrayList productList = ....

theForm.set("product",productList);

//and for some stange reason.. try without the following first

session.setAttribute("product",productList);

...

<logic:iterate id="product" name="productForm" property="product">
        <html:text name="product" property="price" />
...
DynaActionForm theForm = (DynaActionForm) form;
ArrayList productList = (ArrayList) theForm.get("product");
for(int i = 0;i < productList.size();i++) {
        Product prod = (Product) productList.get(i);
        System.out.println(  prod.getPrice()  );        
}
...

This should help.. Cheers Mark

I am wondering what is the best approach to handle
dynamic form fields within an ActionForm.
I have a JSP page that will display quantity input
fields for a dynamic list of products. I don't know
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.
