play 2.1 でコントローラーのテストを実行すると、奇妙な問題が発生します。

    package controllers;

import static org.fest.assertions.Assertions.assertThat;
import static play.mvc.Http.Status.OK;
import static play.test.Helpers.callAction;
import static play.test.Helpers.charset;
import static play.test.Helpers.contentType;
import static play.test.Helpers.status;

import models.Section;
import models.Topic;

import org.junit.Test;

import play.mvc.Result;

public class TopicsTest extends BaseControllerTest{
    @Test
    public void testCallList() {
        Section s = new Section();
        s.name = "Music section";
        s.id = 1L;
        s.description = "section about music";
        s.save();
        System.out.println(Section.find.where().eq("name", "Music section").findUnique().id); // output 1
        Result result = callAction(controllers.routes.ref.Topics.list(1));
        assertThat(status(result)).isEqualTo(OK);
    }
}

コントローラーのコードは非常にシンプルで、dev で動作します。ちょうどよくモード。それを確認してください：

public static Result list(Long id) {
    return ok(list.render(Section.find.byId(id)));
}

Play がモデル クラスのフィールドにアクセスできないようです (getter と setter を生成していないようです)。その場合の非常に明白な解決策は、独自のゲッター (およびセッター) を明示的に記述して、Play が何があってもそれらを見つけられるようにすることです。
