Hi. First, I am Korean. So I don't kow english well. I hope you understand. I want to remove or hide StaticText(Text Field).. I know, It can through "PrintWhenExpression". But I know only 'Main'Parameters, 'Main'Fileds and subreport. I want to remove or hide throught subdata(data in list). Finally(Eventually), I want to hide through field's data in list(empty) Meanwhile, field names in List are $F{title}, $F{content}, etc. I try it "<printWhenExpression><![CDATA[$F{title} != null && $F{title}.trim().length>0]]></printWhenExpression>" And Report Problems Window message "Field not found : title" If you know "printWhenExpression" through field's data in list, please tell me....!
