I installed SonataNews Bundle and Extended it as ApplicationSonataNewsBundle.

When I go to /app_dev.php/admin/sonata/news/post/list

I have the issue message

No metadata found for property ApplicationSonataNewsBundleEntityPost::$tags. Please make sure your Doctrine mapping is properly configured.
500 Internal Server Error - MissingPropertyMetadataException

Someone could help me?

I had similar issue, on my case this was due to class configuration. Mapping is injected during Sf DI, but my custom User Class was not found.

Just check classes used by the News Bundle.
```
sonata_news:
    class:
        post:       ApplicationSonataNewsBundleEntityPost
        comment:    ApplicationSonataNewsBundleEntityComment
        media:      ApplicationSonataMediaBundleEntityMedia
        user:       MyCustomUserBundleEntityUser
```

public function toString( $object )
    {
        return $object instanceof Subcateogry
            ? $object->getSubcateogry()
            : 'Subcateogry'; // shown in the breadcrumb on the create view
    }
