thanks, cool solution. I tried a SQL level solution, but thats nicer.

But: it doesn't work with lazy properties. I got an exception, thats one
argument should be of for example type "Tx...Brand", instance of
Tx_Extbase_Persistence_LazyLoadingProxy given

If I remove the @lazy addition it works, but makes my application slower.

Is that a known bug?
