[TYPO3-mvc] viewHelper for URIs can't access Enviroment

[David Bruchmann]

Hi,

trying to write a viewHelper for extended URI-Handling / -Methods I need 
the enviroment i.e. simply the calling controller-name.
Regrettable the inmormation about this example is capsulated so that I 
don't know how to get the data.
Is there any possibility to get the required Data without changing 
extbase/fluid?

Annotation: as far as I had a look in extbase/fluid classes all 
class-calls are hardcoded and Visibility of variables and methods is to 
restricted in my opinion - if or as long as there aren't enough 
possibilities to retrieve data here I see a grave problem in developing 
a bit more complicated extensions on base of this framework.
But perhaps you can help me and I never remarked a smart way to get more 
data ;)

Thanks,
David
