I don't understand what you mean. I know how to index the properties inside the
iterator tag.but how to declare those properties dynamically in the ActionForm class?

Sorry but I haven't quite catch what you looking for...
Do you want to create a form in runtime? Is that it?
If you're using a DynaForm it already has map. You can't set new
properties to the form (it was built based on a DynaClass) but, if you
extend DynaForm to a XDynaForm and make

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
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
I think I see what you mean. If all you want is a list of product Id's
and the number of units per id, then your priority is to use indexed
properties, rather than DynaForm or normal Form.
If you are using indexed properties, you just name the field one name,
e.g. productId, and the indexing
I'm not sure about one thing though. If I name all of
my inputs on the HTML page the same name, when I
submit the form, won't only one of the inputs be
passed along?

Yes, but because they're indexed, you will see the result as an array.

This worked. :) Do you know if the order is
guaranteed? From my testing it looks like the values
appear in the array in the same order the parameters

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
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
Unfortunately, products can be added at runtime and
therefore I don't know what the full set is. From the
research I have done it sounds like ActionForms can
not handle this situation and I will need to handle it
myself in the Action. Do you agree?

Mark,
Please, correct me if I'm wrong, but I think the action attribute in
the html:form tag is a run time expression, so there's no need to
extend the FormTag class in order to use a dynamic form action.

No, its not a runtime expression.
If you look at the code in FormTag you'll see that its not
results.append(\ action=\);
results.append(response.encodeURL(RequestUtils.getActionMappingURL(action,
pageContext)));
results.append(\);
It simply pulls the action mapping
The code you've quoted has no impact on whether or not the html:form tag's
action attribute is an rtexpr. Look at struts-html.tld:
tag
nameform/name
tagclassorg.apache.struts.taglib.html.FormTag/tagclass
bodycontentJSP/bodycontent
attribute
nameaction/name
requiredtrue/required
All that means is you can have
mysimpleTag value=%=scripletVariable%/
false means you cannot have a scriplet variable as a value
That's not quite what i wanted to do, but in a way accomplishes a similar task without
modifying struts. Its not sexy enough for me ;)

Right, so you'd put the code to determine the appropriate value for the action
attribute in your action, not in a JSP expression. That value could be stored in
a request attribute and accessed simply as:
html:form action='%= request.getAttribute(formaction) %'
html-el:form might even let you do

What do you want to know? I use maps and collections in form beans now to
capture multi-select list key-value pairs and checkbox array booleans,
respectively. I think it would be a simple extrapolation to map
key-values
1. Declare the bean's scope as session as an attribute of the form-bean
declaration in struts-config.xml and provide an empty reset() method in the
bean class;
2. Use java scriplets (though I do not recommend this) as in

Your first statement,
...I have a form that can have N number of images...
Does not warrant the use of nested tag library. Simply use the standard
iterator, and indexed properties of the html:file tag, to properly output
your file names as file[1], file[2], file[3].

Elijah,
Sorry about the lack of the tag. It's on its way.
Pick it up in the next nightly build.

It's difficult to do this in the 1.0.x release, but simple as pie in the
1.1 beta and nightly build.

It may be that this is looking up the original phone number again.
If so, this is also where the recyling message could be coming into it.

In order to use forwards (that depend on the user action), wouldn't you
need some sort of router action class. Would all the pages then call this
class and set some flag to notify it which action to take?
