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。我正在尝试在我的摘要报告中创建一个字段，以便我可以单击它，它将运行并显示详细报告。该字段是：$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，我有以下参数：

_report： 详细信息

reason_id: $F{reason_id}

开始日期： $P{开始日期}

结束日期： $P{结束日期}

当我在摘要报告中单击预览时，我输入了所有参数，然后出现此错误：

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！
