Q: When exactly this method has to be used and when does this get called?
A: The reset method is called for each new request, for both request
and session scoped ActionForms, before the ActionForm is populated
from the request. Here's the sequence of events:
1. Request received by controller.
2.

Reset gets called just before the form is populated and the most common use
is for resetting boolean properties set using checkboxes. This is because if
the checkbox is not "checked" browsers do no submit a value, so the
"population" mechanism doesn't set the property to "false" if the checkbox
is

Why do the checkboxes have to be reset?
Prepopulating the formbean is done in Action class. hence, it's not clear to
me the exact use of using the reset method.
Thanks.
IMO, no.
That should be done in the action as needed. The reasoning for that is
that if you want to reuse the action form for multiple actions (like
with a DispatchAction), no matter what you do, you are rebuilding the
lists which will lead to performance degradation.
If you are using the action
I think that the best sentence to explain when to use the reset method
comes from the JavaDoc: "In practice, the only properties that need
to be reset are those which represent checkboxes on a session-scoped
form." Based on that, I would say that your usage is an inconsistent
usage of the reset()
I am using the reset method in my actionForm classes to get collections of
beans, and then putting them in the request. The JSPs then pull those beans
out to dynamically populate HTML select lists. It works fine, but I'm
wondering if this is the appropriate way to do such a thing?
