Подключаемся к Firebird из Mondrian через JDBC, при работе с другими базами всё нормально, но с Firebird при попытке подключится через JRubik возникают ошибки:

База данных FoodMart стандартная, которая используется Mondrian для теста. Насколько я понял JRubik не может найти потомков в иерархии у кубов Sales, Warehouse and Sales и Sales Ragged. И в мондриане некоторые MDX запросы не выполняются
Вопрос: что мне сделать, стобы исправить эти ошибки.
Заранее спасибо!
