[TYPO3-calendar] realurl title doesn't get updated on change

[Stefan Schreck]

hi there,
I use:

typo3 6.2.9
cal 1.7.0
realurl 1.12.8

when I change the title or use a copied tx_cal_event the RealUrl title 
in the page path doesn't get update.
I cleared the RealUrl Cache and such but in some cases it won't get updated.

Any hints?

In my RealUrl configuration I use:

'GETvar' => 'tx_cal_controller[uid]',
            'lookUpTable' =>
            array (
              'table' => 'tx_cal_event',
              'id_field' => 'uid',
              'alias_field' => 'title',
              'addWhereClause' => ' AND NOT deleted',
              'useUniqueCache' => 1,
              'useUniqueCache_conf' =>
              array (
                'strtolower' => 1,
                'spaceCharacter' => '_',
              ),
            ),
          ),

Thx
Stefan
