Is there a way to compare a field's value to a parameter's value in jasperReport Expression Editor?

Question

I'm trying to print parts of a jasper report conditionally by comparing the parameter supplied value to the value in the field.

However, when I do the comparison the outcome is always FALSE. Both the field and the parameter are INTEGERS. If I compare either of them to an actual number that exists in the dataset, then the outcome is true. Yet, when I supply that same existing number through the parameter for comparison with the field, the outcome is false.

My logic looks like this,

($F{EMPNO}==$P{eno})? "Hello":"Invalid."

Ideally, I expect the word 'Hello' to be printed when the value supplied through the parameter makes the condition true, and 'Invalid' to be printed when the condition is false.

as you will see in dupe you need to compare $F{EMPNO}.intValue()==$P{eno}.intValue() — Petter Friberg, Aug 19 '19 at 13:52

Try placing Boolean.valueOf infront of your parameter. Boolean.valueOf($F{EMPNO}==$P{eno})? "Hello":"Invalid."
