[TYPO3-mvc] Extbase and BE

[Ревенко С.В.]

Does persistence framework work in BE modules?

I try next code

$manufacturer = new Tx_RevaShop_Domain_Model_Manufacturer();
$manufacturer->setTitle('Test manufacturer');

$manufacturerRepository = new
Tx_RevaShop_Repository_ManufacturerRepository();
$manufacturerRepository->add($manufacturer);

but nothing is changes in database. I missing something? Or currently
Extbase persistence framework don't work in BE?

Also, how I can specify in BE pid where records need to be stored?
