collecting parameters from a dynamic form

[Jeff Oberlander]

I have a dynamic form that is built from an ArrayList of objects (see below
(b) ).  Building the form works great.  I get multiple rows of widget names
and values.  However, I can't seem to collect the data in my Action.  The
HTML that is rendered just repeats the same named input fields (see below
(b)).  In my action, my widget ArrayList comes in with the right number of
objects, but they are blank (no data has been collected from the form).  A 

request.getParameter(name));
request.getParameter(value));

works, but of course only returns one of the sets of data - the first in the
form.  So I can't seem to retrieve the multiple values from in my Action
class in any way.  Am I doing something that can't be done?

(a)
input type=text name=name 
input type=text name=value 
 input type=text name=name 
input type=text name=value 

(b)
html:form action=/saveWidgets
logic:iterate id=element name=widgetForm property=widgets
table 
  tr
th 
 Widget Name
/th
td  
 html:text name=element property=name
/td
  /tr
  tr
th 
 Widget Value
   /th
td  
 html:text name=element property=value
/td
  /tr
/logic:iterate
/html:form


Thanks

Jeff

RE: collecting parameters from a dynamic form

The issue is one of distinct element names when you use an iterator to
create your form.  I found the solution by way of the indexed=true
property of html:text  It produces a parameter name of element[0].name -
where element is the name given to the iterator object and the bracket
represents the index of the iterator.  

Apparently this is new though because I had to install the nightly build in
order to use it.

Take a look at the HttpServletRequest API. If you need to get multiple
values for a parameter, you need to use the getParameterValues() method.
