Symfony2 SyliusRbacBundle Setup - symfony

Question

I am exploring the option of using SyliusRbacBundle for my app. I manage to install it along with FosUserBundle. When I got to the setup part I got the following error on running the command 'sylius:rbac:initialize' following the instructions found here: http://docs.sylius.org/en/latest/bundles/SyliusRbacBundle/setup.html#setup-roles-and-permissions-in-the-database
Initializing Sylius RBAC roles and permissions.
Adding permission "Update product". (app.product_update)
Adding permission "Create product". (app.product_create)
Adding permission "Manage product". (app.product_manage)
[Doctrine\DBAL\DBALException]
An exception occurred while executing 'INSERT INTO sylius_role (code, name,
description, security_roles, tree_left, tree_right, tree_level, created_at
, updated_at, parent_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)' with params
["root", "Root", null, "a:0:{}", null, null, null, "2015-05-11 16:45:34",
"2015-05-11 16:45:34", null]:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'tree_left' ca
nnot be null
[PDOException]
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'tree_left' ca
nnot be null
sylius:rbac:initialize
This is how my config.yml looks like:
sylius_rbac:
driver: doctrine/orm
security_roles:
ROLE_ADMINISTRATION_ACCESS: Can access backend
roles:
app.admin:
name: Administrator
description: Administrator
app.product_manager:
name: Product Manager
description: muchos productos
permissions: [app.product_update, app.product_create]
roles_hierarchy:
app.admin: [app.product_manager]
permissions:
app.product_update: Update product
app.product_create: Create product
app.product_manage: Manage product
permissions_hierarchy:
app.product_manage: [app.product_create, app.product_update]
Any one has a clue how to solve it?
Thanks!

The Sylius/Rbac uses the tree behaviour from the Atlantic18/DoctrineExtensions.
You can use this in a Symfony system using the stof/StofDoctrineExtensionsBundle.
Once it has been installed you would need to enable the tree behaviour in your app/config/config.yml like..
stof_doctrine_extensions:
orm:
default:
tree: true
This should make the listener register correctly and then your fields to be auto-populated.
