我有一个与实体ProductLocale关联oneToMany的产品表单，用户可以根据需要添加许多ProductLocale。
html 中呈现的表单似乎是正确的，但是当我收到 POST 数组并执行bind()服务器响应时出现此错误：
"ERROR: This value should be of type Wearplay\WearBundle\Entity\ProductLocale.
但是我发送了两个ProductLocale实体，但验证器无法识别它们。
很明显POST请求包含一个多维数组，其中包含各种实体ProductLocale，但问题是为什么
$form->bindRequest($request)
不能正常工作？
