[platform-dev] Databinding Labelprovider + Chaining

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

[1] shows how to observe a property of an object to have a label 
updating, that works as long as it is a direct property of the (person) 
object.

[2] shows how to chain properties to access "sub-objects" (lets say 
persons address)

But how do I combine both?

IObservableMap streetName = BeanProperties.value(Person.class,
    "adress").value(BeanProperties.value(Address.class,
    "street")).observeDetail(knownElements);

obviously won't work as the "knownElements" are of type 
IObservableSet<Person> ...
