I have Nested field collections 3 levels.

I would like an example how to get to the deeper levels.
I know relations i know views but i cant seem to get to it.

Structure is like this:

user
-- with Field collection (Praktijk)
--some other fields

Field collection (Praktijk) contains
-- Field collection (Praktijk_adres)
-- some other fields

Field collection (Praktijk_adres) contains
-- an Location field
-- some other fields

I need the street of the deepest Location field.
the result is empty for the field on deepest lv in view but when printing the field collection in the same row data is present.

pleas advise
