Expression Variable

[UltraByte]

Hi,

I have a problem with the following expression:

 

$V{PAGE_NUMBER}+(Integer)($P{REPORT_PARAMETERS_MAP}.get("param1"))

 

it is a simple sum in an integer variable, but it gives this error

 

Code:

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class

file: 
1. The operator + is undefined for the argument type (s) java.lang.Integer, java.lang.Integer 
value = (java.lang.Integer)(((java.lang.Integer)variable_PAGE_NUMBER.getValue())+ (Integer)(((java.util.Map)parameter_REPORT_PARAMETERS_MAP.getValue()).get("param1")));

 

can anyone help me ?

 

thanks.

You can do this by converting Integer to BigDecimal (maybe first Integer to String, and then String to BigDecimal), and then use BigDecimal.add() method. I know this is very dirty, but it works and I don't know any other way :) You could use something like

 

(new BigDecimal($V{PAGE_NUMBER}.toString())).add(new BigDecimal($P{REPORT_PARAMETERS_MAP}.get("param1").toString()))

 

I know it's ugly.
