Nontrivial Dozer Mappings

Question

I try my best to get a Dozer to bend my will for something that, in my opinion, should be fairly simple. I have two similar models that I want to compare with each other, but I have a deeper hierarchy than the other, and this causes me problems when working with collections. Consider the following classes:

Source classes:

class Foo {
    String id;
    NameGroup nameGroup; 
    // Setters/Getters
}

class NameGroup {
    private List<Name> names;
    // Setters/Getters
}

class Name {
    private String nameValue;
    // Setters/Getters
}

Target classes:

class Bar {
    private String barId;
    private BarNames barNames;
    // Setters/Getters
}

class BarNames {
    private List<String> names;
    // Setters/Getters
}

Now I need the following one-way mappings:

Foo.id -> Bar.barId // Simple enough

But then I need:

Foo.nameGroup.names.nameValue -> Bar.barNames.names

Therefore, each instance Namein Foo.nameGroup.namesshould result in being added Stringto the list BarNames.names. Is it possible?
