printWhenExpression & java.lang.ClassCastException

[choang]

Hello,

I am running iReport 1.3.3.  And when I compiled my .jrxml file which contains the following code :

...

<printWhenExpression>

   new java.lang.Boolean($P{numTRCBugs} != 0)

</printWhenExpression>

..........

where numTRCBugs is java.lang.Integer

I got the following compile-time error :

"net.sf.jasperreports.engine.JRException: java.lang.IllegalArgumentException: 

Cannot invoke net.sf.jasperreports.engine.design.JRDesignElement.setPrintWhenExpression -

 java.lang.ClassCastException@8b9227"

I wonder if someone could please tell me how to fix this problem?

Thank you very much.

Hi,

 

Try

 

<printWhenExpression>

   Boolean.valueOf($P{numTRCBugs},intValue() != 0)

</printWhenExpression>

 

I hope this helps.

Note the comma, I believe that should be:

 

<printWhenExpression>

   Boolean.valueOf($P{numTRCBugs}.intValue() != 0)

</printWhenExpression>
