Set conditional expression, right way !

[luigi.frasca]

HI,

I have Jasper Reports that it should be print the values in different color according a condition.

So this is my code:

<style name="Style1">
        <conditionalStyle>
            <conditionExpression><![CDATA[$F{OblPL}>0]]></conditionExpression>
            <style forecolor="#FF0000"/>
        </conditionalStyle>
 </style>

and my field is so defined:

<field name="OblPL" class="java.lang.Double"/>

But it does not work, why ? 

 

[reportdev]

try evaluating it a boolean

<conditionExpression><![CDATA[($F{OblPL}>0)==true]]></conditionExpression>

Try this it is working for me.

<style name="style.1pm_CET_UGL" mode="Transparent">
         <conditionalStyle>
            <conditionExpression><![CDATA[$V{Trigger.1pm_CET_UGL}.doubleValue()>0]]></conditionExpression>
            <style forecolor="#FF0000"/>
        </conditionalStyle>
    </style>
