Help with nested groups

2006-02-08 08:24

Hi all!

 

I'm trying to write a report with two nested groups. I have done a master and a subreport because I have two different datasource and the subreport detasource is a field of the master..

 

Essential code:

 

---- Master.xml ----

 

<field name="subreportDataSource" class="java.lang.Object"/>

<parameter name="Subreport" isForPrompting="true" class="net.sf.jasperreports.engine.JasperReport"/>

 

<subreport isUsingCache="true">

<reportElement/>

<dataSourceExpression>${subreportDataSource}</dataSourceExpression> <subreportExpression class="net.sf.jasperreports.engine.JasperReport">$P{Subreport}</subreportExpression>

</subreport>

 

 

 

---- MasterBean.java ----

 

public JRBeanCollectionDataSource getSubreportDataSource() {

 

JRBeanCollectionDataSource subDataSource = new JRBeanCollectionDataSource(

SubreportBeanFactory.getBeanCollection(list));

 

return subDataSource;

 

}

 

 

Is that correct?

If I go in debug with a break in the SubreportBeanFactory and it enters with the correct values for "list" but after few iterations it seems to loop in same place (I don't know where) and doesn't return in the factory..

 

Thanxs!!
