[TYPO3-seminars] cal with cal_ts_service - event view shows no event

[Kerstin Finke]

Hi list,

I installed the cal-extension and cal_ts_service to get a calendar-view 
for my seminars-Manager.
I was happy it worked immediatly without much configuration, I only gave 
him my event-sysfolder, my seminars are shown in month-view and other 
views perfectly. Only one point I cannot solve:

When I click on a seminar I want to go to the detail-view of my seminar.
I only get a "no events found".
(in german: "Momentan konnten leider keine Veranstaltungen gefunden 
werden.")

Here is my configuration:

plugin.tx_cal_controller.display.seminars {
       externalPlugin = 1
       externalPlugin.singleViewPid = 797
       additionalParams = tx_seminars_pi1[showUid]=###UID###
     }

The singleViewPid 797 is my 'detailPID' in seminars.
Not sure whether I need the additionalParams I tried with and without.

I also tried to give the flexform-tab "event-view" my detail-PID, but I 
think it has the same effect like the TS-singleViewPid?!

Who has an idea about this?
Is it right the event-view has to be the detail-PID?

Thanks in advance
Kerstin
