文本字段值中的Jasper Report IF条件 [英] Jasper Report IF condition in Text Field Value

问题描述

使用文本字段值编辑器，我将文本添加有条件的文本(请注意，if是使用JasperSoft studio的字段编辑器构造的，因此代码IF(...)是自动生成的，我只给出了值"pippo"和"pluto")

Using text field value editor i add a text to the text field with a condition (note the if is constructed using the field editor of JasperSoft studio so the code IF(...) is autogenerated, i gave only the value "pippo" and "pluto")

"Some value" +IF(true,"pippo","pluto")

但是似乎不起作用.从我的代码调用报告时出现此错误:

But it seems it don't work. I'm getting this error during calling the report from my code:

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:
1. The method IF(boolean, String, String) is undefined for the type 

任何帮助将不胜感激

推荐答案

尝试使用ternary运算符代替如下所示的IF

Try using ternary operator instead of IF like below

"Some value" + (value == true ? "pippo" : "pluto")

希望这对您有所帮助.
