Typoscript change menu parameter - typo3

Question

I want to generate a menu which changes by a parameter "menu". All menu items have the same pid, therefore the parameter overrideId is set.
So the problem is, the active state doesn't change because I don't change the page. You can see the current script in action via innovisions.artec-berlin.de. It's the menu on the left side.
For some reason the typoscript worked fine in 4.5.2 LTS but not in 4.6.3. Any suggestions or ideas?
