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.
