Hi, I'm trying to get a formatted date into a Jaspersoft Studio Report expression. Some of my data has nulls and some has date completed. I can identify which elements are null and which have dates with an expression like IF(EQUALS($F{adate},null),"N/A",$F{adate}) but if I try and format the date: IF(EQUALS($F{adate},null),"N/A",DATEFORMAT($F{adate},"dd-MMM-YYYY")) I get an error when filling the report (see below) Any ideas how to work around this - I'm driving myself mad ! Thanks in advance I hope !
