[TYPO3-calendar] deleted events - url - Calendar Base Error

[Dirk Fischer]

Hi,

if there is an url in Google index from a deleted event the event detail 
page says:

Calendar Base 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]

How can I fix it, e.g. forward to a page PID?

Best regards
Dirk
