SonataAdmin - The custom block I'm trying to build is not found - php

Question

I'm trying to add a custom block to the dashboard of SonataAdminBundle. I followed the instructinos here (How to add custom link or button to SonataAdminBundle Dashboard in Symfony2) and I'm getting the following error :
RuntimeException: The block service `sonata.block.service.processManagement` does not exist
Here's what I did. I have a file named "ProcessManagementBlockService.php" which contains the following:
<?php
namespace IMA\ProcessManagementBundle\Block;
use Symfony\Component\HttpFoundation\Response;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Validator\ErrorElement;
use Sonata\BlockBundle\Model\BlockInterface;
use Sonata\BlockBundle\Block\BlockContextInterface;
use Sonata\BlockBundle\Block\BaseBlockService;
class ProcessManagementBlockService extends BaseBlockService
{
public function getName()
{
return 'My Newsletter';
}
public function getDefaultSettings()
{
return array();
}
public function validateBlock(ErrorElement $errorElement, BlockInterface $block)
{
}
public function buildEditForm(FormMapper $formMapper, BlockInterface $block)
{
}
public function execute(BlockContextInterface $block, Response $response = null)
{
// merge settings
$settings = array_merge($this->getDefaultSettings(), $block->getSettings());
return $this->renderResponse('IMAProcessManagement:Block:blockProcessManagement.html.twig', array(
'block' => $block,
'settings' => $settings
), $response);
}
}
I also created a file (views/Block/blockProcessManagement.html.twig) that contains the template of the block I want to add to SonataAdmin's dashboard :
{% extends 'SonataBlockBundle:Block:block_base.html.twig' %}
{% block block %}
<table class="table table-bordered table-striped sonata-ba-list">
<thead>
<tr>
<th colspan="3">Newsletter - inviare</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<div class="btn-group" align="center">
<a class="btn btn-small" href="#">Servizio Newsletter</a>
</div>
</td>
</tr>
</tbody>
</table>
{% endblock %}
Also, I in the services.yml file of my bundle, I have the following
services:
# ima_process_management.example:
# class: %ima_process_management.example.class%
# arguments: [#service_id, "plain_value", %parameter%]
sonata.block.service.processManagement:
class: IMA\ProcessManagementBundle\Block\ProcessManagementBlockService
arguments: [ "sonata.block.service.processManagement", #templating ]
tags:
- { name: sonata.block }
I know this file is properly loaded because I tried to put the upper lines directly in config.yml and got the same result.
Finally, I added in the main config.yml file of my project
sonata_block:
default_contexts: [cms]
blocks:
# Enable the SonataAdminBundle block
sonata.admin.block.admin_list:
contexts: [admin]
# Your other blocks
sonata.block.service.text:
sonata.block.service.rss:
sonata.admin.block.search_result:
sonata.block.service.processManagement: ~
and
sonata_admin:
templates:
dashboard: SonataAdminBundle:Core:dashboard.html.twig
dashboard:
blocks:
- { position: left, type: sonata.admin.block.admin_list }
- { position: left, type: sonata.block.service.processManagement}
I really don't know why I'm getting the error that the service does not exist...

The problem is how you did the letter casing in the config.yml. Always use lowercase for defining service names if you don't then Symfony converts it to lowercase.
Take a look at the coding standards for Symfony.
Service Naming Conventions:
A service name contains groups, separated by dots
The DI alias of the bundle is the first group (e.g. fos_user)
A service name contains groups, separated by dots
Use lowercase letters for service and parameter names
