I am trying to dynamically change the language of my report, which is working, when I specify the path like this: Resource Bundels: MyReports/Localization/LocaleReport_de.properties . But if I want to specify the language through a JSON, how could I achieve it? I have tried Resource Bundels: $P{language} with the Parameter language: MyReports/Localization/LocaleReport_de.properties, but it says "java.util.MissingResourceException: Cant find bundle for base name $P{language}" .
How can I control the language of my report through a JSON Input?
