setting a collection in my form bean usin iterate or forEach

[Lynn Stevens <ly...@hotmail.com>]

I was wondering if someone could help me out with this question:

I know that I can use the logic:iterate tag to loop over an existing 
collection
in my form bean.  However, I want to do the opposite.  I want to make
n number of html:textfields and then when the user hits submit, I want to 
have
the information pulled from those n textfields and used to populate a String 
array
or ArrayList or some ordered collection.  If I put a String[] or ArrayList 
in my
DynaActionForm, this does not seem to work.  I have tried to prepopulate
the String[] or ArrayList with n number of empty Strings and this
still does not work.  I am wondering if in fact it might not be possible to 
automatically
do this.  Maybe struts will not pull items from inside an iterate or forEach 
tag
and populate a list.  I need to dynamically lay out the textfields, so I 
won't know in
advance how many I am placing on that page.  This is why I need to put them
within an iterate of forEach tag...

Does anyone know if this is possible?  Its driving me mad!

Thanks in advance,

Lynn

Sure it'll work. Be more specific of how you are setting stuff up (paste 
the dyna/action form definition and the form code. Also, as someone else 
asked, what 'isn't work' - are you getting errors?

Does it throw any exception? The important thing while iterating over
a collection and setting the indexed properties, you have to get the
"property" attribute right.

Take a look at http://struts.apache.org/faqs/indexedprops.html

I have heard that Map-backed ActionForms works in those cases.
