[TYPO3-calendar] Use of a cal service

[Chris Müller]

Hello!

Now I got a step further, the correct invocation of the service is:

$service = t3lib_div::makeInstanceService('cal_event_model', 'event');

But then I got the error:
PHP Fatal error:  Call to a member function isLoggedIn() on a non-object 
in [...]/typo3conf/ext/cal/service/class.tx_cal_nearbyevent_service.php 
on line 46

This is from the rights controller, which is NULL at this stage.

Then I did it with

$service = &tx_cal_functions::getEventService();

which had the same result. Do I have to initialize something before 
using the cal services?

Regards,
Chris.
