So, even though the jsp containing the list of users
and the links to edit each of them doesnot contain a
form tag, your userForm will still be created and
assigned a userID? I guess that is the case due to the
fact that the UserForm is defined for the
DispatchUserAction and has a request scope so the form
will always be created when the action is invoked.
More specifically it's due to the fact that the URL path for the link is
defined in the struts-config action mapping, so yes the ActionForm will
be instantiated by Struts. This is a good point to bring up because many
think you 'have' to use a html form in order to get an ActionForm
populated, but as you have noticed, this is NOT the case. A URL will
work just as well. Good observation.
