Great you managed to get it going. Who was the "TYPO3-freak"? :)

It is not that bad, if you skip the select query and use an API method 
for that as I will show below.

We will be working on that during the Extbase code sprint this weekend.

You could use the object instead. Works fine with all the getters that 
do not have parameters (like getProperty).

change this to to:

$fileObject = $this->typo3FALRepository->findByRelation('<your table 
name>', 'file', $this->getUid());

And it will be much cleaner and not so likely to break as it is a pulic 
API.

'file' here again is the field name defined in TCA.

You can do that, but using the object directly should be fine, too.

Kind regards,
Helmut
