[TYPO3-english] How to add new controller without extension reinstall

[Jan Bednarik]

Hi,

I wonder how is it possible to add e.g. new controller class without 
having to uninstall extension and install it again. I tried deleting all 
caches available yesterday and yet I was still getting that class cannot 
be loaded. The only thing that worked was to go to ext manager, 
uninstall and install.

Thanks

Jan
