JMSSerializerBundle Yaml config for custom entity class - symfony

Question

I've got in my symfony2 project, a custom entity outside Bundles and framework.
I need set json data into this entity, but i can't apply right configuration to user yaml file.
app/config/config.yml
jms_serializer:
metadata:
auto_detection: true
directories:
CORE:
namespace_prefix: "Core\Domain\Model"
path: "%kernel.root_dir%/Resources/serializer/CORE"
app/Resources/serializer/CORE/Model.Product.yml
Core\Domain\Model\Product\Product:
properties:
id:
type: integer
objectId:
type: string
name:
type: string ...
It's possible that this bundle dont works fine with entities outside bundles?.
Always I see error message: You must define a type for Core\Domain\Model\Product\Product::$id.
I think that JMSSerializerBundle don't read yaml file, because with annotations works fine.
Any idea?.
Thanks.

In your app/config/config.yml be sure to use \\ as namespace separator instead of \:
jms_serializer:
metadata:
auto_detection: true
directories:
CORE:
namespace_prefix: "Core\\Domain\\Model"
path: "%kernel.root_dir%/Resources/serializer/CORE"
Otherwise the backslashes are treated as escape characters for the following letters.
Edit:
Also make sure to name the JMS serializer config properly. For the class Core\Domain\Model\Product\Product you need a Product.Product.yml file inside the specified path of the config. In your example, your file is named Model.Product.yml.
So to get the serializer config file name for an entitiy in general:
Strip the namespace defined in the config from the class name
replace the namespace separators \ with .
append .yml and put the file in the path folder defined in the config
