Hi! I download source code of mondrian 3.2.0 and fixed this bug. Download 3 classes from link https://drive.google.com/file/d/0B2lpyZNjLoqieU1zNi1qaE54Y3c and replace in jar /opt/jasperreports-server-cp-5.5.0/apache-tomcat/webapps/jasperserver/WEB-INF/lib/mondrian-3.2.0-13661-JS-3.jar (mondrian/rolap/*)
