Hi, I'm working with iReport 4.0.0 and jasperreports 4.0.0 and I have the problem that language-switching due to the runtime parameter REPORT_LOCALE does not work. Nevertheless what I fill in that parameter - the result is always the same: jasperreport uses the default-locale of my system. The report works as desired if I switch the locale of my windows-pc - but the parameter is always ignored. All I want to do is to transfer the REPORT_LOCALE parameter into the report. I added an additional test-output ($P{REPORT_LOCALE}.toString( ))in the report in order to see whether the arriving parameter value is corresponding to the sending value - and it is!! I can change the REPORT_LOCALE value - but my report does not handle it!! My report always uses the property file according to my system default. It seems that the runtime environment does not evaluate the parameter correctly ??!!Does anyone know this bug and can help me?
