[Catalyst] c->user_exists causes runtime error.

[leonard.a.jaffe at jpmchase.com]

Cats:

The following code snippet:

unless ($c->user_exists) {
     my $standardid = $c->request->header('standardid') || 
$c->request->param('laj');
     unless ($c->login(uc($standardid))) {
        $c->error("Could not authenitcate".  ($standardid ?  ": 
$standardid" : 'UNKNOWN')  );
       return 0;
     }
  }

Generates the following error message: 

[error] Coldn't render template "undef error - Can't call method 
"from_session" on an undefined value at 
D:/Perl/site/lib/Catalyst\Plugin\Authentication.pm line 122.
[error] Caught exception in dtsis::Controller::Root->auto "Can't call 
method "from_session" on an undefined value at 
D:/Perl/site/lib/Catalyst\Plugin\Authentication.pm line 122.
[error] Coldn't render template "undef error - Can't call method 
"from_session" on an undefined value at 
D:/Perl/site/lib/Catalyst\Plugin\Authentication.pm line 122.

along with a debug screen.

What I don't understand, is why it blow up, because the same code snippet, 
with the outermost unless removed (so it calls login on every request) 
works just fine.

I'm using the most current set of authn/'session modules that have come 
through CPAN in last day or two, 
and I'm using Session::Store::DBIC, Authentication::Store::Minimal (due to 
a DBIC/session/freeze issue with
the user record, that I'd posted about already), and 
Session::State::Cookie. 

So, calling login each time is not a big deal for me in terms of resource 
usage, but obviously, I shouldn't really have to.

Any ideas?
