对象“”的方法xyz；SymfonyComponentFormFormView"；不存在

当我将表单移动到窗体类时，我在显示新表单时遇到了问题，我真的不知道该怎么处理这个问题。

我使用Symfony 3.0.4。我认为我从Symfony文档和StackOverFlow中获得了所有信息，但这些数据大多来自Symfony 2.x.

对象"Symfony''Component''Form''FormView"的方法"save"没有存在于FlexPMUsersBundle中：默认值：register.html.twig，位于第8 500行内部服务器错误-Twig_Error_Runtime

我有4个文件：

src/FlexPM/UsersBundle/Resources/views/Default/register.html.twig

{% extends 'base.html.twig' %}
{% block body %}
<div>
    Test
    {{ form_start(formRegister) }}
        {{ form_errors(formRegister) }}
        {{ form_row(formRegister.save) }}
    {{ form_end(formRegister) }}
</div>
{% endblock %}

你知道我能做什么吗？
