What steps will reproduce the problem?
1.

public class Name {
  public String first;
}

public class Person {
  public List<Name> names;
}

public class PersonDto {
  public Map<String, Name> personalNames;
}

And the mapping:

MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
mapperFactory.classMap(Person.class, PersonDto.class) //
        .field("names{first}", "personalNames{key}") // ok
    .field("names{}", "personalNames{value}") // throws exception
    .byDefault() //
    .register();

The mapping:

.field("names{}", "personalNames{value}")

throws the exception:

Caused by: java.lang.ClassCastException: java.lang.Object cannot be cast to 
test.Name

What is the expected output? What do you see instead?

The element from the list "names" should be mapped to the value of the map.

This problem has not been resolved and is particularly frustrating because it is contained in the Orika User Guide: http://orika-mapper.github.io/orika-docs/mappings-via-classmapbuilder.html I would think it incredible that the User Guide code has not been tested, and so I assume there is something missing or that is assumed the new user will know Is it possible to include complete source files for this example - rather than code snippets - to ensure the new user understands? Versions tested are 1.4.2 (as per User Guide) and 1.4.5 (latest)
