Witam,

mam problem z generowaniem raportu uzywając beanów jako źródła danych.

Mam przykładową klase z jednym polem o nazwie "nazwa" typu String, 
odpowiednim getterem i setterem. Tworze jej obiekt, ustawiam wartośc 
stringa.

------------------------------------------------------------------------------
List<MojaKlasa> lista = new ArrayList<MojaKlasa>();
lista.add(new MojaKlasa("jakiś string"));

....
....

InputStream iStream = getClass().getResourceAsStream("raport.jasper");
JasperPrint jp = JasperFillManager.fillReport	(iStream,params,new 
JRBeanCollectionDataSource(lista) );

JasperViewer podglad = new JasperViewer(jp,false);
             podglad.setVisible(Boolean.TRUE);

------------------------------------------------------------------------------

Problem polega na tym, że pole to w raporcie uparcie dostaje nulla.
