[TYPO3-mvc] very complex subpropertyPath

[Philipp]

Hey,

I have seen that propertypaths are cut at 2 levels, what would it take to be able to do such a request:

query->matching(query->contains('occasion.venue.location.rootline',someid))

all other possibilities where i render some properties into their parents are no option for me.

Would it be done by extending the Typo3DbBackend class further (allready included some functionallities)?

has someone done that before?
