I think this should be in the perform() method. If you look at the javadocs,
reset() is called before populating the form fields with the values received
from the HTTP request. This way you can assign default values for fields
that may be missing from the HTTP request.
This is different from the reset() action in the browser's form. When you do
a reset in an HTML form the browser just reloads whatever values were there
originally and does not perform an HTTP request. The fact that both methods
refer to forms but in different contexts is missleading eh?
Cheers,
Jorge
