在Yii中,如何使窗体在对象数组中循环?

涉及的课程:

class ResultForm extends CFormModel {

    /**
     * @var array[Result]
     */
    public $results; //Filled with an array of Result objects
}

class Result {  
    public $requiredArea;
}

<% $form = $this->beginWidget('CActiveForm'); %>
<table>
   ....
   <% $rowCounter = 0; foreach($resultForm->results as $result): %>
       ...
       <tr>
           ....
           <td>
               <!-- This doesn't work -->
               <% $form->textField($resultForm,
                   "results[$rowCounter]->requiredArea") %>

               <!-- Just displaying the value works -->
               <%= $resultForm->results[$rowCounter]->requiredArea %>
           </td>
           ...
       </tr>
       <% $rowCounter++; endforeach; %>
</table>
<% $this->endWidget(); %>

文本字段是呈现的,Yii不会抱怨,但它们不包含正确的值。

有没有一种方法可以实现这一点,或者有没有更好的方法来遍历表单中的对象数组?
