[TYPO3-mvc] Dependency Injection fails only in models

[Christian Peters]

Thank you.

First, I'm having a new problem that I'm trying to solve: Extbase only
stores empty values in the database. Again, I have no idea why :(

However: Validation is not really in option, because it throws an error.
But it's not an error, it's just a decision that I want to make (if this
already exists, use the existing one (reference it), if not use the given
one). I don't think it would be a good idea to solve logical decisions with
throwing errors ...; having it in the controller would make my app unDRY,
as there are multiple controllers accessing the model (the importing
service and the original model controller). Maybe it'd be an idea to merge
the controllers or move the creation logic to someplace else.

Thank you.
