如果之前已经回答过，请原谅我，但我无法在任何地方找到有关它的更多信息。
我在Domino中编写了一些Java，将字段值传递给Jasper报告并生成PDF结果。该报告还包含子报告和子报告。因此，基本上，我得到主报表的字段值列表，其中一个是子报表的字段值数组。在子报表数组的每个记录中，可能存在子报表的另一个字段值数组。很简单。
我的所有Domino数据检索都在一个bean中完成，我在那里初始化了NotesContext，所以我很困惑为什么我仍然会收到这个错误。
就像背景一样......我上周开始学习如何做到这一点，并且能够成功地将硬编码数据传递给PDF。这是我第一次尝试从Domino数据库传递值。
这是获取Domino数据的DataBeanList类：

//this class populates an object array of all the field value objects for the report
//for subreports, there will be multiple objects in the subreport beans, one for each detail band
public ArrayList<DataBean> getDataBeanList(String docnum) {
//create the array to return
ArrayList<DataBean> dataBeanList = new ArrayList<DataBean>();
//this will be a single record array consisting of a series of fields and array of ws subreport
//fields that contains another array of misc subsubreport fields

有人能指出我正确的方向来解决这个问题吗？
更新25APR17，我删除了子报表，它工作得很好！所以，把我的注意力缩小到那个。
