Problema Doctrine - Symfony

[lucho2000]

Cordial saludo.

Estoy empezando a trabajar con Symfony.. me cree una Entidad y al crearla en la Base de Datos con doctryne me genera el siguiente error:

[root@localhost Symfony]# php app/console doctrine:schema:create
ATTENTION: This operation should not be executed in a production environment.

Creating database schema...

[Doctrine\DBAL\DBALException]
Unknown column type "numeric" requested. Any Doctrine type that you use has to be registered with \Doctrine\DBAL\Types\Type::addType(). You can get a list of all
the known types with \Doctrine\DBAL\Types\Type::getTypesMap(). If this error occurs during database introspection then you might have forgot to register all database types for a Doctrine Type. Use AbstractPlatform#registerDoctrineTypeMapping() or have your custom types implement Type#getMappedDatabaseTypes(). If the type n
ame is empty you might have a problem with the cache or forgot some mapping information.



doctrine:schema:create [--dump-sql] [--em[="..."]]



Como lo puedo solucionar ?

Gracias
