Php 条令\ORM\orException：条令2（当前）不支持此行为

我正在运行一个应用程序堆栈，它使用codeigniter和doctrine2。几天前，我成功地运行了命令行工具来生成模型、代理和数据库。那天我对XML映射做了一些补充，现在如果我运行

php doctrine-cli.php orm:create

它给出了以下错误和退出：

[Doctrine\ORM\ORMException] This behaviour is (currently) not supported by Doctrine 2

然而，我做到了

php doctrine-cli.php orm:validate-schema --verbose

这给了我以下信息：

[Mapping]  OK - The mapping files are correct.


[Doctrine\ORM\ORMException]
This behaviour is (currently) not supported by Doctrine 2

orm:validate-schema

有人能告诉我这里有什么问题吗

注意：我的实体和代理生成时没有任何问题

编辑：当我发现问题时关闭此对话框，它只不过是映射中定义的关系造成了问题

当实体映射出现问题时，通常会发生此错误。例如：

    /**    
    * @OneToMany(targetEntity="Task", mappedBy="")
    */
    private $task

此处未指定上面的mappedBy属性，这将导致此错误
