[TYPO3-mvc] How to filter output when n:1 relation between objects?

[Roland]

i tried this ("3" is hardcoded to keep the example simple) in 
ProductController.php:

$products = 
$this->productRepository->findByBrand($this->brandRepository->findByProducer(3));

i get this error message:

--- quote ---
Fatal error: Call to a member function findByProducer() on a non-object 
in 
/Users/roland/projects/project-001/typo3conf/ext/rolandproducts/Classes/Controller/ProductController.php 
on line 68
--- /quote ---

any suggestions?
