我有一份JasperReports的报告，其中有几个子报告。我在我的NetBeans中使用iReport插件。我已将相同的整数参数类型传递给所有子报表以及主报表。主报表有两个参数，一个启用了提示选项，类型为字符串。另一个将参数作为字符串并将其转换为整数Integer.parseInt($P{MEMBER_CERTIFICATE_PARAM_MAIN})（这可以在所有子报告中找到）。这就是我总是传递参数的方式。但是当我运行此报告时，我会收到以下错误。

2 个答案:

答案 0 :(得分：2)

问题是你宣布了

<parameter name="MEMBER_CERTIFICATE_PARAM_SUB"...>

，默认值

<defaultValueExpression><![CDATA[Integer.parseInt($P{MEMBER_CERTIFICATE_PARAM_MAIN})]]></defaultValueExpression>

甚至在声明$P{MEMBER_CERTIFICATE_PARAM_MAIN}之前。事实证明，文件正在从头开始读取，所有表达式在读取时都在评估。在评估"MEMBER_CERTIFICATE_PARAM_SUB"报告时，我不知道$P{MEMBER_CERTIFICATE_PARAM_MAIN}是什么。
