[Contrib: Evaluation System] Redirect direct links to login

[Marc Savitsky]

Hi,

We have direct links to allow users to take an evaluation.  These are of 
the format 'http://localhost:8080/direct/eval-evaluation/16'.  The user 
is redirected to login if necessary.

We also use direct links to view the evaluation results, the url being 
similar 'http://localhost:8080/direct/eval-reports/16'.  However this 
time there is an error message (and a  UserNotDefinedException) if the 
user is not logged in.

Does anyone know how I would go about changing the view results action 
so that the user is redirected to login if necessary.

We run version 1.3 of the evaluations tool.

Many thanks
