I tried it, but it doesn't work. Is there any problem if the 
FileCollection gets accessed through a ViewHelper?

I do the same in my gallery:

inject FileCollectionRepository

findByUid($uid)

loadContents() --> empty!

Thats my problem right here, I was checking on the media_gallery but the 
only problem is, that I use a ViewHelper for it, everything else is the 
same.

Is there any additional typoscript setup necessary?

I will try moving all to the Controller itself.

Thanks,
Dominic
