iReport: вложенные отчеты (источник данных XPath XML) не повторяют записи

У меня работают вложенные отчеты, но снова и снова отображается только первый элемент в каждом вложенном отчете.

So data formatted like this:           Looks like this

    A                                   A
      1                                   1
      2                                   1
      3                                   1
    B                                   B
      4                                   4
      5                                   4
      6                                   4
    C                                   C
      7                                   7 
      8                                   7

Вау, спасибо. У меня все еще есть проблема. Вывод в подотчете представляет собой одну строку нулей. Я проверил и перепроверил, что я сделал правильные изменения. Я использую iReport 4.1.3. - person FlappySocks; 22.11.2011
