[TYPO3-mvc] how to add/remove related object in an m:n relation?

[Roland]

omg, that was easy.

$item->addCategory($category);

and

$item->removeCategory($category);

as far as i remember, these methods are called something like "magic 
methods". thanks to my IDE which showed me that there exist these methods.

kind regards.
