Hi,

I have classes:

class Master {
    @Id
    String id;

    Detail detail;

    public Master(String id) {
        this.id = id;
    }
}

@ValueObject
class Detail {
    String data;
    Detail subdetail;

    public Detail(String data) {
        this.data = data;
    }
}

and test code:

        Master master = new Master("1");
        master.detail = new Detail("detail-1");
        master.detail.subdetail = new Detail("subdetail-1.1");
        master.detail.subdetail.subdetail = new Detail("subdetail-1.1.1");
        javers.commit("anonymous", master);

I know how to read first level ValueObject changes:

        List<Change> changes = javers
                .findChanges(QueryBuilder.byValueObjectId("1", Master.class, "detail")
                        .withNewObjectChanges(true)
                        .build());

but how to read second, third, ... - any level VO changes/snapshots?

f.e.

        List<Change> changes = javers
                .findChanges(QueryBuilder.byValueObjectId("1", Master.class, "detail/subdetail")
                        .withNewObjectChanges(true)
                        .build());

              "dummyAddress/networkAddress").build())
