Cakephp3 - 找不到引发错误的 $theme 属性

Question

我已经从 Cakephp3 v3 升级到 v3.3（使用 Composer），但出现以下错误：

Deprecated (16384): Property $theme is deprecated.
Use $this->viewBuilder()->theme() instead in beforeRender().
[CORE/src/View/ViewVarsTrait.php, line 103]

但是我在我的文件中找不到使用 $theme 的地方。我已经在我的所有文件中搜索关键字 $theme 和 beforeRender，没有相关结果。

这个错误出现在我的所有页面中，所以它一定是每个页面中包含的某个文件。

我已经在 google 上搜索过这个问题，也没有相关结果。

有其他人遇到过这个问题吗？

事实证明，在 AppController 中，自定义主题（在我的例子中是橙色）需要声明为：

public function beforeRender(Event $event)
{
    $this->viewBuilder()->theme('Orange');
}

不喜欢

public $theme = 'Orange';

非常感谢@arilia 帮助我。
