Symfony2/Doctrine2.4 "It's a requirement to specify a Metadata Driver" - php

Question

I want to use some of the features of Doctrine 2.4 (mainly named entity listeners) and $event->properyHasChanged('property') and updated my composer.json to this collection:
"require": {
"php": ">=5.3.3",
"symfony/symfony": "~2.4",
"doctrine/orm": "2.4.3",
"doctrine/doctrine-bundle": "~1.3",
"twig/extensions": "~1.0",
"symfony/assetic-bundle": "~2.3",
"symfony/swiftmailer-bundle": "~2.3",
"symfony/monolog-bundle": "~2.4",
"sensio/distribution-bundle": "~2.3",
"sensio/framework-extra-bundle": "~2.3",
"sensio/generator-bundle": "~2.3",
"incenteev/composer-parameter-handler": "~2.0",
"stof/doctrine-extensions-bundle": "dev-master",
"friendsofsymfony/jsrouting-bundle": "~1.1",
"friendsofsymfony/rest-bundle": "dev-master",
"sprain/validator-bundle": "dev-master",
"willdurand/geocoder-bundle": "#stable",
"friendsofsymfony/user-bundle": "~2.0#dev",
"escapestudios/wsse-authentication-bundle": "2.3.x-dev",
"jms/serializer-bundle": "dev-master",
"doctrine/doctrine-fixtures-bundle": "2.2.*",
"luxifer/doctrine-functions": "dev-master"
},
The composer.phar updates without problems until the end.
After updating or when I try to use any console method (or the symfony2 app) I'm getting this error:
[Doctrine\ORM\ORMException]
It's a requirement to specify a Metadata Driver and pass it to Doctrine\ORM\Configuration::setMetadataDriverImpl().
My Doctrine configuration is as follows:
doctrine:
dbal:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
charset: UTF8
orm:
auto_generate_proxy_classes: %kernel.debug%
entity_managers:
default:
auto_mapping: true
Rolling back to doctrine 2.2 works.
Is there a good example of symfony2 and Doctrine 2.4? Because even in the current version (2.6 of Symfony2 they are using an older version of Doctrine.
Any help is appreciated!

Answer 1

The default configuration as stated in the Doctrine Bundle docs is as follows:
doctrine:
orm:
auto_mapping: true
# the standard distribution overrides this to be true in debug, false otherwise
auto_generate_proxy_classes: false
proxy_namespace: Proxies
proxy_dir: %kernel.cache_dir%/doctrine/orm/Proxies
default_entity_manager: default
metadata_cache_driver: array
query_cache_driver: array
result_cache_driver: array
As you can see it adds a Metadata Driver of type array.
Try and see if this solves your problem.
