Hello, I'm using list to display data grid of the report. I would like to display the message "no data available" below the column headers when there is no data return in the list. I also would like to show "n/a" when some of the data fields are not avaliable. I'm using text field expression below to show "n/a" but it's not working. it displays blank. <textFieldExpression><![CDATA[$F{status}==null?
