I've finally had some time to look at creating Jifty::Plugin::Login (based
completely on the login bits in Wifty) and I'm at a bit of a brick wall.  It
seems like the call to Jifty->api->allow (in J::Plugins::new_request) isn't
affecting the application's list of allowed actions.  I've confirmed that
J::P::Login::new_request is being called (by creating a wrapper), but even if I
replace it with the exact same code that is in the base class, nothing is being

For example, using the Tutorial website, I added this to etc/config.yml:

    - Login: {}

and I added the following to Jifty/Plugin/Login.pm:

sub new_request {
    my $self = shift;
    my $class = ref($self) || $self;
    my @actions = Jifty::API->new()->actions();
    print STDERR Data::Dumper->Dump(\@actions);

and what displays in the console window when I hit the site is:

$VAR1 = 'Jifty::Action::Autocomplete';
$VAR2 = 'Jifty::Action::Redirect';
$VAR3 = 'MyWeblog::Action::CreateLogin';
$VAR4 = 'MyWeblog::Action::CreatePost';
$VAR5 = 'MyWeblog::Action::DeleteLogin';
$VAR6 = 'MyWeblog::Action::DeletePost';
$VAR7 = 'MyWeblog::Action::UpdateLogin';
$VAR8 = 'MyWeblog::Action::UpdatePost';

which agrees with what displays if I put something similar in the index.html
page.  If I try and hit the /login action, I get:

ERROR - Can't locate MyWeblog/Action/Login.pm in @INC (@INC contains:

which confirms that the allow isn't happening.

What am I missing???
