Hi, I am trying to change the color of a fields value that is it a table. And the fields are part of a sub-dataset. I have tried the Conditional Styling Tags but when i add the style tags to the reportElement I get an error saying "Field not found: XML_ANSWERS --- net.sf.jasperreports.engine.design.JRDesignExpression@33ef232a" my style tag : <style name="failColor" fontName="SansSerif"> <conditionalStyle> <conditionExpression><![CDATA[$F{XML_ANSWERS}.equals("fail")]]></conditionExpression> <style mode="Opaque" backcolor="#FF0000"/> </conditionalStyle> </style>
