Hi all, I am currently using jasperserver 5.6.1. I have a mandatory field in my report, which when I view the report, it prompts me to input and there show a message "This field is mandatory so you must enter data.". The input field has a default "[NULL]" display, I try to get rid of it by setting the parameter with <defaultValueExpression><![CDATA[""]]></defaultValueExpression>. Since then the mandatory message disappeared even though the control input mandatory checkbox is still checked. Does anyone has any idea? Thanks for help! Justin
