Not work for self reference

[tuonglx]

It works well for

public class MainTest {
    public static void main(String[] args) {
        ModelMapper modelMapper = new ModelMapper();
        Parent p = new Parent();
        p.name = "1";
        Order order = new Order();
        order.name = "2";
        order.parent = p;
        OrderDTO dto = modelMapper.map(order, OrderDTO.class);
        System.out.println(dto.parentName);
    }
}
class Order {
    String name;
    Parent parent;

}

class Parent {
    String name;
}

class OrderDTO {
    String name;
    String parentName;
}

but does not work for

class Order {
    String name;
    Order parent;
}

@tuonglx - Sorry for the lately reply...
I think self reference is always complicated and not easy to handle.
Maybe you can try our explicit mappinp.

If you are using ModelMapper v1.0.0 with java 8, then you can do this.

modelMapper.typeMap(Order.class, OrderDTO.class).addMapping(
  src -> src.getParent().getName(),
  (dest, value) -> dest.setParentName(value));

Or for old school style, you can try this

modelMapper.addMappings(new PropertyMap<Order.class, OrderDTO.class>() {
  protected void configure() {
    map().setParentName(source.getParent().getName());
  }
});

And thanks for the report! I will close this issue, and feel free to leave comment if you still have some problem.
