TYPO3 Core

I extended the sys_file_metadata table with an inline field to add some object relations to a file's meta data. This doesn't work for normal users (admins have no problems). By adding a new Relation with the ajax call comes an error and no relation is generated. This causes an "access denied" pop up for the user.

I found the reason for this in the class TYPO3\CMS\Backend\Form\Element\InlineElement. The function checkAccess() returns false in every case because of these lines (2111 to 2114):

$calcPRec = BackendUtility::getRecord('pages', $this->inlineFirstPid);
if (!is_array($calcPRec)) {
    return FALSE;
}

$this->inlineFirstPid is 0 in case of adding an inline element.

The popup message is called in line 1266 in the createNewRecord() function (TYPO3\CMS\Backend\Form\Element\InlineElement), which is called by ajax in this case.

$item = $this->renderForeignRecord($parent['uid'], $record, $config);
if ($item === FALSE) {
    return $this->getErrorMessageForAJAX('Access denied');
}
