[TYPO3-mvc] Dependency Injection not working

[Claus Due]

Hi Alex,

1) Did you clear the object reflection cache? If you're on 4.5 you must do this manually. If the error has been happening for more than an hour then this is -not- the cause.

2) Does ApplicantRepository implement t3lib_Singleton? It should, if you wish to utilize injection.

3) If none of the above then are you able to manually construct an instance of ApplicantRepository using ObjectManager?
