空索纳塔管理实体列表视图

I got a weird result using the Sonata Admin -- list view. Here is the snapshot.

config.yml:

    # ...

sonata_admin:
    title: Administration
    title_logo: extras/fi.gif

sonata_block:
    default_contexts: [cms]
    blocks:
        # Enable the SonataAdminBundle block
        sonata.admin.block.admin_list:
            contexts:   [admin]

services.yml:

# ...

services:
    sonata.department.admin:
        class: %sonata.department.admin.class%
        tags:
            - { name: sonata.admin, manager_type: orm }

DepartmentAdmin.php

<?php

namespace Abc\Bundles\HelloBundle\Admin;

use Sonata\AdminBundle\Admin\Admin;

use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;

class DepartmentAdmin extends Admin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->with('Department')
                ->add('name')
            ->end();
    }

    protected function configureDatagridFilter(DatagridMapper $datagridMapper)
    {
        $datagridMapper->add('name');
    }

    protected function configureListFilter(ListMapper $listMapper)
    {
        $listMapper->addIdentifier('name');
    }
} 

Entity\Department.php

//...
public function __toString()
{
    $name = $this->getName();
    return empty($name) ? 'Add Department' : $name;
}

The thing is, I did not integrate SonataUserBundle with this project as I find it inappropriate to the spec. Any ideas why am I getting an empty list view? For some reason, the configureListFilter is not called.

Shame on me! the issue is with the function name

configureListFilter

It should be

configureListField

waaah!.. took me long to realize that typo crap.. Thanks @AldeeMativo for the help
