Hi All!  
This is not a problem in general but i’ve just missed the point.  
If my application has a global state, which i have to use both  
throughout ActionController and ActiveView, then, where to place that  
state?  
E.g. if I do this:

class ApplicationController \< ActionController::Base  
protected  
def authenticated?  
!user.nil?  
end  
end

then I can’t use that from any View. And, on the other hand, if I do  
write that as a public method - it acts as an action…

So, where to place such “global” properties?

Thanx a lot!
