PHP Zend子表单-查看子表单元素上的脚本装饰器

我有一个products表单（请在此坚持），它有一个子表单，由product数组索引标识，每个子表单都包含另一个子表单（子表单异常）由产品ID标识，此子表单包含一个多复选框，该复选框显示每个产品两个选项：选择产品并将其标记为免费

当我添加任何类型的装饰器（理想情况下，我希望添加自定义视图脚本）时，都不会输出任何内容（没有错误）。当我没有为元素指定装饰器时，它会输出表单

布局如下

products sub-form [
    selection sub-form [
        MultiCheckbox element[
            decorator[
                ViewScript[]
            ]
        ]
    ] 
]

这是我的表格。有可能以这种方式实施吗

<?php

/**

我的decorator的语法有点错误，缺少一个外部数组。下面是装饰师应该做的：

'decorators' => array(
    array(
        'ViewScript', array(
            'viewScript' => '/admin/partials/property-products.phtml',
            'category' => 'services',
            'options' => $product
        )
     )
)
