FileLoaderImportCircularReferenceException when adding subdomain routing to Symfony - php

Question

I am trying to route a subdomain to a specific bundle in Symfony2. Here's what I've got:
I added local domains to my hosts:
127.0.0.1 todolist.lc
127.0.0.1 manager.todolist.lc
I created a virtual host that forwards all subdomains to my Symfony installation:
<VirtualHost 127.0.0.1>
ServerName todolist.lc
ServerAlias *.todolist.lc
DirectoryIndex app_dev.php
DocumentRoot "C:\xampp\htdocs\todolist\web"
</VirtualHost>
I created a new Bundle to handle the subdomain manager.todolist.lc:
Now I am trying to set up the route to manager.todolist.lc:
frontend:
resource: "#FrontendBundle/Controller/"
type: annotation
prefix: /
backend:
resource: "#BackendBundle/Controller/"
type: annotation
prefix: /api
manager:
host: manager.todolist.lc
resource: "#ManagerBundle/Controller/"
type: annotation
prefix: /
Now after I added the manager route I get a FileLoaderImportCircularReferenceException on every route there is.
I also tried to use a prefix, but this also gives the Exception:
manager:
resource: "#ManagerBundle/Controller/"
type: annotation
prefix: /manager
I can't figure out what I am missing. What am I doing wrong? If you need any more info, just ask for it in the comments and I'll provide it.

Ok. Here's what I was missing:
1. I forgot to load the bundle into the AppKernel
Obviously, this is very important:
new FrontendBundle\FrontendBundle(),
new BackendBundle\BackendBundle(),
new ManagerBundle\ManagerBundle(),
2. The subdomain needs to be declared before the main domain
After I loaded the bundle into the AppKernel the application would still route to the FrontController. I solved this by changing the order of my routes:
manager:
host: manager.todolist.lc
resource: "#ManagerBundle/Controller/"
type: annotation
prefix: /
frontend:
resource: "#FrontendBundle/Controller/"
type: annotation
prefix: /
backend:
resource: "#BackendBundle/Controller/"
type: annotation
prefix: /api
After changing the order of the routes both manager.todolist.lc and todolist.lc worked.
