unload（）CakePHP Uploader插件似乎不起作用

我正在使用CakePHP 2.1.1和Miles Johnson的Uploader Plugin v 3.5。
雖然我覺得在嘗試卸載FileValidation行爲時遇到問題，但它的工作非常好。unload（）CakePHP Uploader插件似乎不起作用

我已經設置了行爲Uploader.Attachment和Uploader.FileValidator（請參閱問題的底部）。
在afterSave回調中，我現在需要再次保存Post以爲其他語言環境添加翻譯字段。

當我再次保存時，這似乎會在FileValidation行爲中導致en錯誤。我得到的錯誤：
failed to open stream: No such file or directory [APP/Plugin/Uploader/Model/Behavior/FileValidationBehavior.php, line 296]
不知何故行爲正在再次尋找tmp文件。
當我根本沒有定義FileValidation行爲時，一切都很順利。所以我想在我的第二個save()之前，在正常的save()期間完成它的工作之後禁用它的行爲。
在afterSave($created)因此，我聲明

$this->Behaviors->unload('FileValidation'); 
$this->save($data);

錯誤消失，但我得到4個警告回報：

Warning (512): Could not find validation handler maxWidth for file [CORE/Cake/Model/Model.php, line 3155] 
Warning (512): Could not find validation handler maxHeight for file [CORE/Cake/Model/Model.php, line 3155] 
Warning (512): Could not find validation handler filesize for file [CORE/Cake/Model/Model.php, line 3155] 
Warning (512): Could not find validation handler required for file [CORE/Cake/Model/Model.php, line 3155]

我也試過$this->Behaviors->disable('FileValidation')但無濟於事。這是行爲錯誤（不正確卸載自己）還是我沒有正確處理卸載？

親切的問候，巴特
