Implementing Dynamic Forms, mixing Struts tags with plain HTML controls...

[Michael Marrotte]

I got the JSP, found below,  to work within my application for implementing
dynamic forms.  The HTML <select>'s are "named" dynamically with Struts
<bean:write>'s, all within <logic:iterate>.  The Action that handles this
form processes the HttpServletRequest, filtering for parameters names that
start with the constant values, e.g.  "withholdingAmount_".  Since the
"names" in each row of the iteration are suffixed with the same key, e.g.
countyNumber-caseNumber, the parameters can be associated and processed
accordingly in the Action.

While this works, I get the feeling I'm re-inventing the wheel.  Is there a
100% Struts technique that renders this type of dynamicism? Any thoughts are
greatly appreciated.

Thanks,
