Crosstab and printWhenExpression

2006-01-10 15:49

I have a crosstab and only want to print it on certain instances. I tried adding a printWhenExpression element to the reportElement, but the compile fails. It passes the check from the dtd. jasper reports 1.1.1

 

Here is how I am using the tag:

 

<crosstab isRepeatColumnHeaders="false">

<reportElement x="0" y="20" width="812" height="60" mode="Opaque">

<printWhenExpression><![CDATA[new Boolean(true)]]></printWhenExpression>

</reportElement>

...

 

Here is the stack trace

That's a bug. Here is the fix: go to net.sf.jasperreports.engine.JRExpressionCollector, find this method:

public void collect(JRCrosstab crosstab)

and add this line at the beginning:

collectElement(crosstab);

 

The fix is also available on CVS.

 

Regards,

Lucian

thanx, that seems to work. It compiles now.
