私は私が最終的に出てアイロンをかけてしまったいくつかのパスの問題がありました。その後、私は新しいエラーが発生しました。 java.lang.IllegalStateException：によって引き起こさ

ノードのデータはありませんタイプ：org.hibernate.hql.ast.tree.IdentNode - [IDENT] IdentNode： 'E' {originalText = E}

ありますこのエラーの場所はありません。どこに行くのかわかりません。

Answer 1

E（r.roleTypeを選択、S、E）が、その参照その明確ではないがあります：おそらく...うーん

@NamedQuery(name = Schedule.QUERY_EVENTS_BY_USER, query = "SELECT r.roleType, s,e " + 
                   "FROM Schedule s, ScheduleRole r, SystemUser u " + 
                   "WHERE u.email = :email " + 
                   " AND u.id = r.systemUserId " + 
                   " AND r.scheduleId = s.id " + 
                   " ")
