[TYPO3-seminars] TX:seminars - Fatal Error in class.tx_seminars_pi1_registrationEditor.php

[JCL - Johannes C. Laxander]

Hello,

when I click a Link for register to a seminar, I get this Fatal Error:

Call to undefined method SJBR\StaticInfoTables\PiBaseApi::getCurrentLanguage() in /../typo3conf/ext/seminars/pi1/class.tx_seminars_pi1_registrationEditor.php on line 1148

Any idea? Bug? Configuration problem?

TYPO3 6.0.6, seminars 0.9.5.

Johannes.
