[TYPO3-mvc] FAL - create FileReference from within a frontend controller action

[Jan Kornblum]

Hi newsgroup,

how can a FileReference be created inside a controller action from a 
given file (stored anywhere in fileadmin)? I've got a model containing 
a property $images (ObjectStorage of FileReference) with all its 
neccesary getters and setters. TCA definition is correct, too, using 
getFileFieldTCAConfig.

Is there already a native way to accomplish this in 6.2? I've found 
different workarounds, some dated one year back or more... And one 
example using a typeconverter, which seems too complex for my case.

Thanks a lot and kind regards, Jan
