using as sub-module: preview caused "property of non-object' caused by $module->customConversion

[MetaCrawler]

Hi,

When I use the editor as sub-modue inside a module/extension with own configuration and executing the preview I reicve:

PHP Notice 'yii\base\ErrorException' with message 'Trying to get property of non-object' 
in D:\basic_project\vendor\kartik-v\yii2-markdown\controllers\ParseController.php:31

All other functions (for example the downloads) are working like expected. When I use the configuration in app/config/web.php instead of the extension config - the preview works without any problems.

My extension / module is configured like described in the yii2 guide: http://www.yiiframework.com/doc-2.0/guide-structure-modules.html

My Module.php looks like this:

namespace app\modules\test;

class Module extends \yii\base\Module
{
    public function init()
    {
        parent::init();

        $this->modules = [
            'markdown' => [
                'class' => 'kartik\markdown\Module',
                'previewAction' => 'markdown/parse/preview',
                'downloadAction' => 'markdown/parse/download',
            ],
        ];
    }
}

Is this a bug or did I something wrong with the configuration as sub-module?

Thank you and best regards
