Subject: Re: when not to use an ActionForm
Hello, Martin/Andy:
I'd like to suggest using JSTL for this type of scenario. You can find a
nice explanation at the following URL (my compliments to its author):
http://jakarta.apache.org/struts/faqs/indexedprops.html
Regards,
Oswald
Note: I also downloaded the tag-libs project, because the solution outlined
in the preceding URL requires both jstl.jar and standard.jar, which contains
org/apache/taglibs/standard/lang/support/ExpressionManager.class

I don't believe it can be done with the fields named like that, but there is
a trick you might be able to use. ;-)
1) In the [input] elements, use names of the form "dynaFields.field_1", etc.
The name isn't important, but the dot is.
2) Create a corresponding Map property in your form bean (i.e. a property
named "dynaFields" in this example).
When your action form is populated, you will end up with the "dynaFields"
map containing key/value pairs corresponding to the name/value pairs from
your [input] elements.
