Yeah, you're right... Shame on me ;)

Youre ballroom_dancing is already in my list of "have a look at how it's 
done there"-extensions ;) You're referring to your additions to the 
persistence layer?


Unfortunately, i get some strange errors upon installing (using current 
4.4 SVN and extbase/fluid SVN):

- Some tables can't be created / updated from extension manager

- when viewing a list of dances or figures:
Fatal error: Call to undefined method 
Tx_Extbase_Persistence_Mapper_DataMapper::injectPersistenceManager() in 
/Applications/XAMPP/xamppfiles/htdocs/typo3/typo3conf/ext/ballroom_dancing/Classes/Persistence/TcaSelectItemFactory.php 
on line 42

- when viewing list of recordings:
#1251315966: Could not determine the type of the contained objects.

Tx_Extbase_Persistence_Exception_UnexpectedTypeException thrown in file
/Applications/XAMPP/xamppfiles/htdocs/typo3/typo3conf/ext/extbase/Classes/Persistence/Mapper/DataMapper.php 
in line 521.

I will try to fix those and adopt your solution to my extension.
Thanks for the hint!

(Don't bother the file path: I've checked out extbase separetely, since 
i get some strange SVN messages when updateing core with the reference 
to the external extbase-repository)

Greets,
