I require this to limit the Print when Expression Field on Jasper Studio.
I had some trouble getting the comparison formule, because I used the typical:
$F{rfq_c} == "VALUE"
This formula did not work because it only applies when comparing strings.
After a lot of trial and error the correct formula would be:
new Boolean($F{rfq_c}.booleanValue() == true)
To compare a couple of strings in JasperReports (Java)
$F{issotrx}.contentEquals("Y") ? "SO #" + $F{albaran} : "PO #" + $F{albaran}
