I'm trying to fill a report with empty datasource like this
JasperPrint print = JasperFillManager.fillReport(@"D:\ImagesReport.jasper", null);
Usually the program crashes without notice, but I used watch window and found that this is what I get
at net.sf.jni4net.jni.JNIEnv.CallStaticObjectMethodPtr(Class clazz, MethodId methodIdNative, Value[] args)
at net.sf.jasperreports.engine.JasperFillManager.fillReport(String par0, Map par1)
in D:\jasper4net\Jasper4net\net\sf\jasperreports\engine\JasperFillManager.generated.cs:line 149
