[TYPO3-dev] Model Class __construct() never called

[g4-lisz at tonarchiv.ch]

Hi Stephan,

thank you for your help. I finally got the injection of ObejctManager
working. I didn't realize that I have to inject the
ObjectManager_Interface_, and that there is a new option "flush system
cache", which has to be enabled for the BE user.

Hence I don't need __construct() or initializeObject() anymore.
But __construct() still doesn't get called at all for this object. Even
if I delete all caches. Strange...

So it's perfectly fine to use t3lib_div::makeInstance to reach out for the objectManager itself. But t3lib_div::makeInstance doesn't trigger any dependency injection (not injecting settings, not calling inject* methods, not analyzing @inject annotations) mechanisms. ObjectManager->get does.
