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

[Stephan Schuler]

Ah, and here's another one.

You should avoid t3lib_div::makeInstance and use the objectManager->get instead. T3lib_div::makeInstance reuses singletons if they already exist. 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.
So always use objectManger->get, never t3lib_div::makeInstance.

Probably because the object is not constructed
