I know, I held my nose when doing that, but in point of fact, it does work,
so in a pinch....

For some unknown reason, I was never able to get the redirect formatting
worked out, so I resorted to smelly workarounds. That works nicely, thank
you.

My bad, sorry, that's from a debug message *somebody* coded into my app
(sigh).

But likely I don't have the go formatting correct. He's not picking up the
user id:

.--------------------------------
| Action
+--------------------------------
| /auto
| /user/base
| /user/id
| /user/blog/base
| /user/blog/id
| /user/blog/entry/base
| /user/blog/entry/add
|  -> /user/blog/entry/save
|   /auto
|   /user/base
|   /user/id
|    -> /user/not_found
|     -> /user/list
| /end
|  -> Blog::View::TT->process

I've tried various incarnations of go, but here's one:

    my @args =3D qw( $user_id  $blog_id );
    my @captures =3D $c->req->captures;

    $c->go( 'Blog::Controller::User::Blog::Entry', 'list', [ \@captures,
\@args ] );

I also tried with my @captures =3D (), @captures =3D  qw( $user_id  $blog_i=
d );

I don't see go yet.
