You've got it backwards. In your example the `list', `template' and `view'
actions all map to `/templates'.

You should have something like:

  package MyApp::Controller::Templates;

  sub template :Chained('/') :PathPart('') :CaptureArgs(1) {...}
  sub list :Chained('template') :Args(0) {...}
  sub view :Chained('template') :Args(0) {...}

See

chType/Chained.pm#Introduction for a good example.

`$c->response->redirect($c->uri_for('templates'))' should work, since it's a
path relative to the current controller. The uri_for method should prepend
the URI with your app's base URL and the path to the controller, so that
should be all you need.
