How to use printWhenExpression in JasperReports

Question

Can somebody tell me how to use the printWhenExpression of JasperReports?

Answer 1

You can also use the static method "Boolean.valueOf(boolean b)". It does exactly the same logic as "($F{mesure}.startsWith("PH") ? Boolean.TRUE:Boolean.FALSE)" and good rule of thumb is don't recreate the wheel.

Boolean.valueOf($F{mesure}.startsWith("PH"))

Boolean.valueOf($F{userfd4}).equals("1"))
