[TYPO3-mvc] How to get to typoscipt ?

if it's not working I'd say it's probably a bug and we missed that spot 
when making use of the objectManager - but I'll have to check that.

I haven't dug to deep in the DI implementation of extbase yet, I only 
know that there is currently only limited support for lifecycle methods 
and IIRC it's not planned to add those - but they are available in 
FLOW3. The only method getting triggered I know of is "initializeObject" 
  (if available in the object of course).

Well, if the objects that should be injected are singletons (implement 
t3lib_Singleton), you of course will get the very same instance 
everywhere, but scopes are AFAIK not supported in extbase (but in FLOW3 
IIRC).
