title: Subreport trouble in iReport 0.4.1
body: <p>I am using <em>iReport 0.4.1</em> and <em>JasperReports 0.6.3</em>, and I'm facing the trouble trying to generate a <em>subreport</em>:</p>
  
  <ul>
  <li>I set in Java code <em>.jasper subreport</em> path, it's correct, but putting wrong path for test, no errors happen;</li>
  <li>In subreport, putting a field for test, again no errors happen (i.e., the <em>subreport</em> is not accessed...);</li>
  <li>I tried to access <em>subreport</em> list by two ways: as parameter and as a main report bean field (it's not the case: in fact I have two not-related reports to print in the same page, so that's why the <em>subreport</em>);</li>
  <li>In almost all tries, when didn't happen error, appears a blank where <em>subreport's</em> data had to be </li>
  <li>PS.: I put the <em>subreport</em> in <em>Detail</em> band, with main report data.</li>
  </ul>
  
  <p>Could somebody help me? - both reports code below.</p>
  
  <p>PS 2: I can't change versions, it's a new report in an existent structure, with this <em>iReport</em> and <em>JasperReports</em> version.</p>
  
  <p>Java report calls:</p>
  
  <pre class="lang-java prettyprint-override"><code>parameters.put("subreportPath", projetoPath + "&lt;CAMINHO&gt;\\" + "xxxzz.jasper"
  .................
  parameters.put("ListaComparativoSaldos", listaSubreport);
  //ABAIXO: nao funcionou
  //parameters.put("ListaComparativoSaldos", new JRBeanCollectionDataSource(listaSubreport));
  .................
  return JasperFillManager.fillReport(is, parameters, new JRBeanCollectionDataSource(data));
  </code></pre>
