[TYPO3-mvc] How to define a userdefined dispatcher???

[David Bruchmann]

Hi,

I want to define an own dispatcher but have some problems doing so:

1) calls to dispatcher are hardcoded at many places
2) an own dispatcher included in ext_localconf.php isn't executed
3) I don't know where I have to call my own dispatcher and to retrieve 
the results

My dispatcher shall extend the usual dispatcher-class, so it isn't 
completley new nevertheless I don't know how to call my own dispatcher.

Thanks,
David
