Hi all,

I've gone over this and re-wrote my Controller three times now.  I'm
looking for a best practice suggestion.

My Coldsping managed, Service Layer pattern MVC app uses a Controller
that listens for a login action.  The login form uses username/password
pair and I want to get into the habit of validating input prior to
authenticating the login credentials.

In the spirit of keeping a Controller primarily logic free, I originally
requested a userId from my UserService passing in the form variables. If
the return value was not 0, I hit the Service again for a User instance
and then pass the instance on for the view to use. Using this method, I
could provide a response that the login is bad (0), but not if the
required form input is valid.

After that, I tried having my UserService return either an object or an
array of errors (yikes!).

Now, I'm validating the form variables in the Controller prior to
passing them to the UserService and it still feels fishy to me.

What if I ask the service for a User object, set the username and
password, then ask the object to validate the input?  If the input is
valid, I send the object back the Service for authentication. If
authenticated, carry on.  If not authenticated, prepare an error message
and pass error to view for display.

I'm modifying Illudium PU-36 generated CFCs for my model (stripping down
the validate() method into validatelogin()).  

Also, I plan to roll js validation on the front end as well, but I want
implement server side validation first.
