TYPO3 Core

I've created a little workaround for this problem which works without the action_getUserMainDir.

I've changed action_createDir in \sysext\sys_action\Classes\ActionTask.php to the following:

protected function action_createDir($uid) {
        // Get path
        $path = $GLOBALS['TYPO3_CONF_VARS']['BE']['userHomePath'];

        // Get the uid
        $storageUidPos = strpos($path,':');
        $storageUid = substr($path,0,$storageUidPos);

        // Create an storage repo instance
        $storageRespository = GeneralUtility::makeInstance('\TYPO3\CMS\Core\Resource\StorageRepository');

        // get the storage by uid
        $storage = $storageRespository->findByUid($storageUid);

        // get the userHomePath in the storage
        $folder = $storage->getFolder('/'.substr($path,$storageUidPos+1));

        // create a new one
        $folder->createFolder($uid);
    }

Everything missing now are some checks if the path and the storage uid are set and of course if the storage and user home path does exist. I would like to add those checks but I'm to stupid to debug it :-x so please someone else add some if conditions like in the original action_getUserMainDir() including the "lockRootPath"-check.

Thanks!
