[TYPO3-mvc] Interfaces or abstract classes as action arguments?

[Dennis Ahrens]

Hi list,

what's about having a action that can handle each object of a parent 
type given as interface or abtract class. While digging through the code 
it seems to me as if this is not possible right now.

What do you think of handing over the object class as GET/POST and using 
this information for reconstruction - if the action just gives an 
interface/abstract class as parameter description?

regards
Dennis
