[TYPO3-dev] EXTBASE :: Domain model inheritance for entities

[Steffen Wickham]

Hello Philipp,

I'd like to thank you for your help! :)
After a week I'd stay in bed, I got everything up and running. All types
of questions can now be entered and extends the base object. For the
normal backend user it is a really nice and easy way to enter all data
through the IRRE fields. I wouldn't archieve it without your help!

I just get messed around with the repository for the quiz, maybe you
could help me another time, please?! :)
Every time I execute a query on the quiz and try to get the questions, I
only get a ObjectStorage object full of "Question" objects but expect to
get the right child classes like "MultipleChoiceQuestion" within the
result set. If I do a var_dump on the objectStorage, it will even dump
the correct type-field like:

["type":protected]=>
        string(41) "Tx_LgQuizbasetypes_MultipleChoiceQuestion"

I only added a Repository for the Quiz object itself but no one for the
Question base class nor each kind of Question.

Do you know how I can fix that so I get the correct Question object
through the QuizRepository?!

Thanks again!
Steffen
