tom_45 Posted February 28, 2019 Share Posted February 28, 2019 Hi,Whenever I try to use a built-in function in Jaspersoft studio, I have an error like this one:Error evaluating expression for source text: UPPER($F{nett_content_value})I have this in the Expression field of a text field:UPPER($F{nett_content_value}) Is the syntax wrong?

hozawa Posted March 13, 2019 Share Posted March 13, 2019 The syntax is correct. Check if $F{nett_content_value} is of type String. Upper only works on String and causes error on other data types. Link to comment Share on other sites More sharing options...
