That is mainly because your model does not have an mm-relation. *g*

Does this listview work? Domain_Repository_Person->findAll();

That's not gonna work. I think one person can be in more then one 
appartement (otherwise you would not use mm-relation). Then this has to be:

@var Tx_Extbase_Persistence_ObjectStorage<Tx_Test_Domain_Model_Department>

You can't store multiple departments in one department-object, you have 
to use an objectStorage for that.

has to be objectStorage as well ...

this is no mm-relation. you don't use an mm-table and you use maxitems 
=> 1 (which then indicates 1:1 or n:1 relation)

that wouldn't work with mm-relation either. person.department would be 
an objectStorage and you could iterate that with f:for-viewhelper in fluid.

First of all you have to decide, wether to use mm or not. If you want 
your person to be in just one department at a time, forget about 
mm-relations and -table and use n:1 relation with select and 
maxitems=>1. Otherwise you have to configure your TCA right according to 
the MM-parameter and use objectStorages.

I hope so ;-)
