[TYPO3-mvc] DataMapper bypasses dependency injection in domain model object

[Jan-Erik Revsbech]

Hi list, I'm currently trying out the new Extbase 1.3 bundled with TYPO3 
4.5.

I'm especially trying out the new Dependency Injection (DI) things, but 
have a problem. I have a domainmodel Tx_Mocshop_Domain_Model_Address 
which has a injectObjectManager(Tx_Extbase_Object_ObjectManagerInterface 
$objectManager)  methods. This works great if i create a new instance of 
the model with 
$objectManager->create("Tx_Mocshop_Domain_Model_Address"); then the 
correct objectManager, is automatically injected into my address domain 
model. However if I do a

$rep = 
$objectManager->get("Tx_Mocshop_Domain_Repository_AddressRepository");
$address = $rep->findByUid(1);

The injectObjectManager methods on address object is not called.

I debugged it into the datamapper, in the mapSingleRow method. Here it 
calls createEmptyObject which does a $object = unserialize('O:' . 
strlen($className) . ':"' . $className . '":0:{};'); and thus bypasses 
the objectmanager and the DI.

One solution would be to use $object = 
$this->objectManager->create($className); Instead, but I guess that 
would be quite a perfomance penalty. Another solution would be somehow 
duplicate what the ObjectContainer does and inject needed classes into 
the domain model.

Or is dependency injection in domain model just not supported currently?
