Subreports

2005-02-04 00:59

Hi, I have yesterday read whole day this forum and not found any solution to my problem.

 

I have one report and this report read data from Custom Datasource which is exteded from JRAbstractBeanDataSourceProvider. For example, I fill this DataSourceProvider with JRBeanCollectionDataSource(collection).This collection contains Bean CustomerImpl.

 

Now I would like to add to bean CustomerImpl this getter.

 

public Collection getServices() {

}

 

and this return collection associated to the Customer. This collection data i would like to display into subreport on customerPage.

 

Whole report shows collection of Customers and their collection of services...

 

I am confused what I have to return to the subreport.

I have set in subreport the dataSourceExpression ? But I dont know which type have to be this expression . DataSource (i.e. JRBeanCollectionDataSource) or BeanDataSourceProvider (i.e. JRAbstractBeanDataSourceProvider)...

 

Thanx for any suggestion...
