[Seasar-user:12728] Re: dbfluteでのDBアクセスについて

[kubo]

久保です。

MainPage.javaの49行目はどこでしょうか？
そこでNullPointerが発生しているようです。

もし、「bhv.selectList(cb);」の行なのであれば、
BehaviorがPageクラスにインジェクションされていないのだと思われます。

試しに「public ProfilesBhv bhv;」を「public ProfilesBhv profilesBhv;」
にして実行して頂けますでしょうか？
publicフィールドの場合はフィールド名が
そのままコンポーネント名として扱われるような気がしたので...
