我在 iReport 中向下钻取时遇到问题

Question

我有两个报告：Summary 和 Detail。它们都位于同一个目录中，我正在尝试在 iReport 5.0.1 中执行此操作。我正在尝试在我的 Summary 报告中创建一个字段，以便我可以单击它，它将运行并显示 Detail 报告。该字段为：$F{reason_id}。

在摘要报告中，我在其中一个字段中创建了一个超链接，如下所示：

超链接目标： 自我

超链接类型： ReportExecution

在我的链接参数中，我有参数：

_report： 详情

reason_id： $F{reason_id}

开始日期： $P{开始日期}

结束日期： $P{结束日期}

当我在 Summary 报告中单击 Preview 时，我输入了所有参数，然后出现以下错误：

将您的报告表达式更改为完整路径，例如“/reports/folder/detail”，并确保在报告名称周围包含引号！
