Description

An exception will be thrown when expanding an inline entity which is a one-to-many relationship to the entity itself.

My entity model:
@EdmEntityType
@EdmEntitySet(name="Manufacturers")
public class Manufacturer {

@EdmKey
@EdmProperty
private String id;

@EdmProperty
private String name;

@EdmProperty
private Calendar founded;

@EdmNavigationProperty
private List<Car> cars;

@EdmNavigationProperty
private List<Manufacturer> subManufacturers;

}

Request: http://localhost:8080/PqmODataExample/PqmODataExample.svc/Manufacturers('1')?$expand=SubManufacturers

Response:
{"error":{"code":null,"message":

{"lang":"en","value":"Not implemented"}

}}

A workaround is to add toRole to the navigation property annotation as "@EdmNavigationProperty(toRole="r-manufacturers")".
