[TYPO3-dev] Use FAL in own extension, StorageRepository object not working

[Klaus Hinum]

Hi,

just tried the new File Abstraction Layer in an own extension and I dont 
get it to work.
I can create an instance using
$s1 = 
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('\\TYPO3\\CMS\\Core\\Resource\\StorageRepository');
but the object I get only has protected functions and e.g. getByUid is 
not available.
Do I have to check if the FAL was initialized first. I cant find a good 
tutorial. The one in docs.typo3.org doesnt work at all (outdated?) and 
the snipped in the presentation of Typo3 6.0 has errors and leads to the 
problem of the empty object.

Regards
Klaus
