You are pretty much on the money with what the discussion is about;
it's not possible to 'generate' a form in the manner you mention here,
but you can sort of 'simulate' that; what I am doing on the petstore
app for instance, requires that every cart item be shown as part of
the cart form... this in itself is something rife easily allows you to
do by having a a value placeholder and blocks that you can iteratively
process and append per bean instance... the added complexity comes in
because as per the cart reqts, I have to have a quantity textfield
that allows the user to update qty per item.
rife currently supports a getSubmissionBean(BeanType.class) method
which allows you to easily get an instace of the bean returned from
teh form, and do validation against that... it would be nice (and I
might have to look into this) to be able to make a similar call, only
this time to retrieve a list/array of the beantype you require.
Currently, I am sending back parameters in my submission; like:
submission name=process
param name=id /
param name=iid /
param name=quantity /
/submission
and using getParameterIntValues(paramString) call in my Element
implementation to iterate over these values and recreate the beans
just as I would have expected a call to a proposed getSubmissionBeans
to have worked.
We might hv to think this through and see if it's possible/feasible to
implement something of the sort as a feature of the framework.
Cheers,

Emmanuel,
I join this discussion a little bit late, I guess, but I thought what I
had to share might be useful to you.
Why don't you create a CartBean class that has array properties?
For example:
class CartBean {
private String[] ids; // assuming your ids are of type String
private String[] iids;
private long[] quantities;
... and so on
}
Then, in your template, whether you use JavaScript or not, use the same
names as the properties in your bean for your input controls.
getSubmissionBean(Class) is clever enough to fill in array values into
the properties of the submitted bean, which you can then process.
In short, you shouldn't have to use a bean per item; you need only use
one bean for the cart.
Regards,
Eddy

Re: [Rife-users] array/multiple beans from form submission
Hi Geert, Actually, what you can do if you really want to isolate and componentize the handling of these beans, you can use embedded elements and provide it with a data object during processEmbeddedElement (which will be each bean). This is only supported in 1.5 though. Indeed, I am using embedded elements for this, and on 1.5 too; I had, however, been using the method of forcing the embedding element to implement an XXXBeanProvider interface to store an instance of the item to be processed by the embedded element, but this new method is more elegant; I saw a mention of it in the changelist for 1.5, but it did not make sense until now... sweet! What this means then is I have to iterate over the quantities sent, and push them into the bean instances, and then just pass these on to the embedded elements and do validation on those. Would have been nicer if we could do a getSubmissionBeans(BeanType.class) call in this regard, but this shd work for me now.

Geert, the embedded elements and do validation on those. Would have been nicer if we could do a getSubmissionBeans(BeanType.class) call in this regard I don't really follow, how would that work? there's already a getSubmissionBean(BeanType.class) implementation... which prepulates a bean with param values... I was just thinking aloud on if we could have a getSubmissionBeans(BeanType.class) imp where a ListBeanType is returned instead, as happens to be what, in a sense, I am trying to achieve here.

Re: [Rife-users] array/multiple beans from form submission
Hi Emmanuel,
1// how do i locate which bean a particular quantity maps to when the
form is submitted;
1.1// changing the form method to a GET, with 2 items in the cart (one
with qty 1, the other with 4), i get a submission uri that looks like:
http://localhost:8080/$%7Bv%20SUBMISSION:FORM:submit/%7D?
quantity=1quantity=4update.x=34update.y=17
These should normally respect the order of the beans that you used to
create the cart items. Can you use that? Another alternative is to
add a hidden form tag with the id of the bean.
2// is there a way to use the id of the input with form submissions
2.1//rife doesn't seem to allow nested value tags.. ideally, i wanted
to use the id of the cartitem as it's id. so, it would have been nice
to be ablel to do:
${v FORM:INPUT:quantity}id=${v id/} style=text-align: right;
maxlength=3 size=3${/v}, but rife barfs at this.
${v FORM:INPUT:quantity}id=${v id/} style=text-align: right;
maxlength=3 size=3${/v}
can be written as
${v FORM:INPUT:quantity/}
${bv FORM:INPUT:quantity}id=${v id/} style=text-align: right;
maxlength=3 size=3${/bv}
that should give you what you're looking for
Added support for nested value tags is planned but I sadly haven't
got enough time to get everything done. RIFE could really benefit
from some new framework developers ;-)
Hope this helps,
Geert

Re: [Rife-users] array/multiple beans from form submission
Geert,
As always, thx for the quick response;
1// how do i locate which bean a particular quantity maps to when the
form is submitted;
1.1// changing the form method to a GET, with 2 items in the cart (one
with qty 1, the other with 4), i get a submission uri that looks like:

create the cart items. Can you use that? Another alternative is to
add a hidden form tag with the id of the bean.
Yes, I figured that the order is maintained and yes that works; i
guess what I am kinda wondering is how I to get validation/error
marking working with my current template.
2// is there a way to use the id of the input with form submissions
2.1//rife doesn't seem to allow nested value tags.. ideally, i wanted

yup; perfect! thx

true.. it's been crazy busy around here (which is why even petstore is
still not up); but plans to add/improve bits of the framework have
alywas been right up there :)
thx,
