Hi all,

i'm using fileUpload inside outputPanel. After the upload, the information of uploaded files disappears from list. Relevant code:

<a4j:outputPanel id="opUpload" ajaxRendered="true">
<rich:panel id="pnUpload" binding="#{testFileUpload.pnUpload}" />
</a4j:outputPanel>

 public TestFileUpload() {
 FacesContext fc = FacesContext.getCurrentInstance();
 this.pnUpload = new HtmlPanel();
 this.pnUpload.setStyle("background-color: blue; width: 400px; margin-left: auto; margin-right: auto;");

 HtmlFileUpload fu = new HtmlFileUpload();
 fu.setMaxFilesQuantity(5);
 fu.setListHeight("100px");
 fu.setListWidth("400px");
 Application app = fc.getApplication();

 ValueBinding vb = app.createValueBinding("#{testFileUpload.files}");
 fu.setUploadData(vb);

 Class[] args1 = {UploadEvent.class};
 MethodBinding mb3 = app.createMethodBinding("#{testFileUpload.listener}", args1);
 fu.setFileUploadListener(mb3);

 this.pnUpload.getChildren().add(fu);
 }

If i take out the outputPanel, it works perfectly. But i really need the outputPanel as a "wrapper". Any suggestion? Thanks.
