I don't really understand what you are asking, but I think you are
saying that you want to email a link to a secure page to someone who
must log in before viewing the page.

For security you can either write your own session validator class or
do your security checks in your screen class in the isAuthorized()
method (the screen class in your example above would either be
SOME.java or Default.java) and redirect the user to your login
template.

Assuming you are doing your security checks in your screen class, try
the following code...
context.put("nextTemplate",
data.getScreenTemplate().replace('/',','));
... you can then access this from your login template as $nextTemplate.
Note, you will also need to pass any request parameters across to the
screen you are redirecting to.

Try setAction("Login").setPage("$YYY") instead.
