[TYPO3-project-seminars] Using Hook in Version 0.6

[Oliver Tempel]

Hi,
after Upgrading to version 0.6, modifySingleView doesnt work.
Reporting follwing error:
Fatal error: Cannot access protected property 
tx_seminars_seminar::$recordData in 
/var/www/vhosts/tutoren-muenchen.de/httpdocs/typo3conf/ext/msv_seminars/class.seminars_modifySingleView.php 
on line 13

Try to access some new db entries:
$sem->seminar->recordData['public'];

Whats wrong?
Greetings
Oliver
