java - iReport 计算表达式时出错

我们正在使用 iReport 5.0.1,并已成功转换我们的许多 Crystal Reports 包。

我正在处理混合了整数和 double 据类型的数据,并且在详细信息部分的变量字段内执行计算。

然后我有 3 个变量对详细数据求和。第一个变量是它上面的细节变量的直接和。第二个根据 IF..THEN..ELSE 语句添加一个参数或第二个参数,第三个根据类似的 IF..THEN..ELSE 语句减去完全相同的参数值。

我需要对组页脚中的 3 个变量字段进行舍入,因此我将 Math.round(variable_name) 应用于这 3 个变量中的每一个。原始的和最后一个(减去参数)都工作得很好。中间变量(添加参数)抛出错误,“错误评估表达式:Math.round(variable_name)”。如果我去掉格式,它运行正常。

我复制并粘贴了工作变量,将其重命名为正确的名称,以确保我没有遗漏最初设置它们的方式,但无济于事。当我使用空数据源运行它时,它运行了,但当然没有数据。

这会让我相信数据有问题,但我已经检查过了,数据对数据源都是有效的,没有 NULL、空白或字符数据。

此时我很困惑。该报表在 Crystal Reports 中编译和运行得很好,使用的函数非常接近。

如果有人有任何建议,我很乐意倾听,我将在下面发布报告的 XML。

提前感谢您提供的任何帮助。

米。斯奈德
