[TYPO3-calendar] Show hidden events on eventViewPid (cal)

[Stefan Var]

Hello,

I try to watch events which are hidden.
If I use the "save&show" button in the event-datarecord in my sysfolder the 

plugin.tx_cal_controller.view.event.eventViewPid = 22

redirects me to the right page (pageid 22).
But then i receive an error:

Message: Missing or wrong parameter. The event you are looking for could not be found.
Note: Please verify your URL parameter: tx_cal_controller[uid]

If I check the "show hidden contentrecords" in my AdminPanel it's still the same error.

Any suggestions?

Thanks
