Is it possible to bind a tableviewer to a model and its sub objects, for example using properties?

eg: my model consists of

public class Person {
public String name;
public List<Address> addresses;
}

public class Address {
public String postcode;
}

I would like my tableviewer to display column 1 Persons name, column 2 first address postcode, column 3 second address postcode etc etc.

Hi Matt,

if addresses is implemented by WritableList you could use a ComputedValue
and get the first/second/etc. element from the list. if you have multiple
persons you would need a ComputedMap. The writable list is needed to
automatically update the computed value/map upon changes in the list.
