Ah I see. That's really interesting. You call it defaultAction, that 
implicies that there are othere Actions possible.
So does the TS replace the php-code or is it an alternative ?
Also i don't see - how are parameters handled in TS ? Looks like you do it 
in array, where does return values processed ?
How does simple switch-case works with the TS ?
Sorry for asking so lot, but i think the TS in general needs some more 
functionality to work on such high level. In this case TS is used like a 
programming language, and i wouldn't call TS a programming language (atm).
