学说形式元素 + zf3 错误 messaje "No object manager was set"

Question

我使用学说来创建我的表单中的doctrinemodule form element element objectSelect。但是向我展示了这些错误："没有设置对象管理器"。我基于学说模块指南。我有时间搜索，但无法找到什么错。代码：

表格：

<?php
//.....
use DoctrineModulePersistenceObjectManagerAwareInterface;
use DoctrineCommonPersistenceObjectManager;
use ZendFormForm;
class SubRubroForm extends Form implements ObjectManagerAwareInterface
{
    private $value_submit;
    private $objectManager;
    public function __construct($value_submit)
    {
        $this->value_submit=$value_submit;
        // Define form name
        parent::__construct('SubRubro-form');
        // Set POST method for this form
        $this->setAttribute('method', 'post');
        $this->addElements();
        $this->addInputFilter();
        $this->init();            
    }
    public function init()
    {
        $this->add([
            'type' => 'DoctrineModuleFormElementObjectSelect',
            'name' => 'rubro',
            'options' => [
                'object_manager' => $this->getObjectManager(),
                'target_class'   => 'RubrosEntityRubro',
                'property'       => 'nombre',
            ],
        ]);
    }
// ... add others elements addElements(){} ....
// ... inputfilters ....
// ... set and get ObjectManager() interface methods...
}

添加父亲类元素的init（）方法。

类Subrubroform扩展表单实现ObjectManagerawareInterface {private $ value_submit;私人$ objectmanager;

public function __construct($value_submit)
{
    $this->value_submit=$value_submit;
    // Define form name
    parent::__construct('SubRubro-form');
    // Set POST method for this form
    $this->setAttribute('method', 'post');
    $this->addElements();
    $this->addInputFilter();
    $this->init();            
}
public function init()
{
    $this->add([
        'type' => 'DoctrineModuleFormElementObjectSelect',
        'name' => 'rubro',
        'options' => [
            'object_manager' => $this->getObjectManager(),
            'target_class'   => 'RubrosEntityRubro',
            'property'       => 'nombre',
        ],
    ]);
    parent::init();
}
// ... add others elements addElements(){} ....
// ... inputfilters ....
// ... set and get ObjectManager() interface methods...
