Expression Editor Help?

[raysefo]

Hello,

 

What i want to do is, i have a field and if this field is NOT NULL, then count.

 

Here is the code below;

 

if($F{KISI_ID}.intValue() != null){

$V{count}.intValue()= $V{count}.intValue() + 1;

}

 

But it gives errors;

 

it.businesslogic.ireport.gui.logpane.ProblemItem@10e1ea8 Syntax error on token "(", ; expected Line 48, Column 23 /jasperReport/variable[1]/variableExpression[1] and

 

it.businesslogic.ireport.gui.logpane.ProblemItem@1feb264 Syntax error on token ")", delete this token Line 48, Column 23 /jasperReport/variable[1]/variableExpression[1]

You want to do this

 

( $F{KISI_ID}.intValue() != null ? $V{count}.intValue() + 1 : 0 )

 

or

 

( $F{KISI_ID}.intValue() != null ? $V{count}.intValue() + 1 : $V{count}.intValue())
