This project is created to demonstrate RestyGWT bug of failed compilation. This happens when response type declaration contains nested generic types.
public interface RestyGwtService extends RestService {
@POST
@Path("/test.json")
Request test(MethodCallback<ResponseDto<List<EntityDto>>> aCallback);
}
public class ResponseDto<T> {
private boolean successful;
private T data;
public boolean isSuccessful() {
return successful;
}
public void setSuccessful(boolean aSuccessful) {
successful = aSuccessful;
}
public T getData() {
return data;
}
public void setData(T aData) {
data = aData;
}
}
public class EntityDto {
private Long id;
public Long getId() {
return id;
}
public void setId(Long aId) {
id = aId;
}
}The following error is shown after compilation:

At the same time, the following code will work without any problems (only one generic is used in response type):
public interface RestyGwtService extends RestService {
@POST
@Path("/test.json")
Request test(MethodCallback<ResponseDto<EntityDto>> aCallback);
}
