Hi Bastian,
Hmmm... Sorry, I still don't get it. Perhaps you could explain the 
following example:

class Tx_MyExt_ThisClass
     extends Tx_Extbase_DomainObject_AbstractValueObject
{
     public function injectThatClass(Tx_MyExt_ThatClass $thatClass)
     {
         $this->thatClass = $thatClass;
     }
}

class Tx_MyExt_ThatClass
     extends Tx_Extbase_DomainObject_AbstractValueObject
     implements t3lib_Singleton
{
     public function __construct(Tx_YourExt_SomeClass $someObject)
     {
         $this->setSomeObject($someObject);
     }
}

As you can see I have a class "ThisClass" which needs to inject 
"ThatClass", but ThatClass's constructor takes an argument. If ThatClass 
hasn't been instantiated how will the the DI container be able to 
instantiate ThatClass without being passed it's constructor parameter? 
Are you saying the DI container will automatically "get" the constructor 
parameter for ThatClass and that I cannot pass the parameter for 
ThatClass's constructor to the DI container?

Thanks!
