Question

I store user.displayName in the session, when users authenticate:

session.put("udn", user.displayName);

and the template renders it using:

${session.udn}

but strange things occur:

1. login as “Sam”, display “Sam”;
2. logout;
3. login as “Jim”, display “Sam”, too!
4. restart play;
5. login as “Jim”, display “Jim”;
6. logout;
7. login as “Sam”, display “Jim”, too!

That is, it always display the first logged in user’s displayName.

debug just after the session.put:

session.put("udn", user.displayName);

Logger.debug("udn:\t" + session.get("udn"));

it prints correctly:

• login as Sam, prints “udn:Sam”;
• login as Jim, prints “udn:Jim”

also, I checked the cookie:
PLAY_SESSION contains %00udn%3A + correct value + %00:

• login as Sam, PLAY_SESSION contains %00udn%3ASam%00
• login as Jim, PLAY_SESSION contains %00udn%3AJim%00

How do I display the correct value? (my play app depends on play 1.2.3 & Secure module)

You should be using ${session.get("udn")} in your template. The implicit session variable is just an instance of play.mvc.Scope.Session; there’s no magic in place that would allow syntax like ${session.udn}. I’m not sure why that prints anything at all.
