Wrong code in getting started tutorial
In Chapter 8. Controller there is wrong/old code inside SetupController class.
The example shows
$blog = $this->objectFactory->create('F3\Blog\Domain\Model\Blog');
but this property doesn't exist. The current way is to use
$blog = $this->objectManager->create('F3\Blog\Domain\Model\Blog');
I found this error in the example of the GettingStarted package (in Private/CheatSheet/code) too.
