Why is mojolicious "routing to a callback" ?

pcouderc has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks, I am trying to authenticate and I success :
sub startup { my $self = shift; my $r = $self->routes; $r->get('/:layout')->to('login#nolog'); $r->get('/:layout/logout')->to('login#logout'); my $auth = $r->under( sub { return defined($self->session('userid' +)) } ); $auth->get('/:layout/menu')->to('login#menu'); $r->any('/:layout/:dummy')->to('login#nolog');}
I authenticate in Login.pm sub nolog, I define userid and I redirect to "upsmichel/menu", I expect "login/menu.html.ep" to be rendered but instead I am routed to a callback ?
why ? What do I miss ?
Thanks

    Can you maybe show us a small, self-contained example that we can use to replicate your problem? Something that has a minimal login/menu.html.ep and the minimal code to reproduce?

      Mmm, minimum, it is trivial with : Login.pm
      package Myapp::Controller::Login; use Mojo::Base 'Mojolicious::Controller'; sub nolog { my $c = shift; $c->session(userid => 1); $c->redirect_to('menu'); } 1;
      and nolog.htlm.rp :
      %= form_for nolog => (method => 'POST') => begin <p> % if (param 'user') { <b>Erreur dans le mot de passe ou le nom d'utilisateur. Veuillez r +éessayer</b><br> % } Utilisateur :<br> %= text_field 'user' <br>Mot de passe :<br> %= password_field 'pass' <br> %= submit_button 'Login' </p> % end
      and login.htlm.ep :
      <p> ... </p>
      Self contained, I do not know how to do (I am not with Mojolicious::Lite)..
        Does Class "MyApp::Controller::Login" is not a controller mean anything to you?

    "Routing to a callback" means calling a "sub { ... }" instead of a to('somecontroller#someaction'). If you give it a name it will print the name instead of just "a callback". (conversely, you can embed any of them with a sub{} callback instead of a name and it will say just "Routing to a callback" instead of "Routing to controller/action".

    It is probably calling your $r->under() sub and failing.
      Thank you.
