rich:uploadFile + a4j:mediaOutput - can't get it working

[sambolino]

greetings!

could anyone possibly detect what am i doing wrong here? i'm trying to keep it simple here - during creation/editing of an employee entity upload a jpg and show it

<a4j:mediaOutput id="mediaout" element="img" mimeType="image/jpeg"
 createContent="#{employeeService.paint}" session="true"
 value="#{employeeService.employee.picture}"
 style="width:100px; height:100px;" cacheable="false" />
 <rich:fileUpload fileUploadListener="#{employeeService.listener}"
 id="upload" immediateUpload="true" acceptedTypes="jpg"
 listHeight="60px" autoclear="true">
 <a4j:support event="onuploadcomplete" reRender="mediaout" />
 </rich:fileUpload>

methods inside conversational bean:

public void listener(UploadEvent event) throws IOException {
 File file = event.getUploadItem().getFile();
 InputStream in = new FileInputStream(file);
 byte[] data = new byte[in.available()];
 in.read(data);
 employee.setPicture(data);
 }

 public void paint(OutputStream out, Object obj) throws IOException {
 out.write(employee.getPicture());
 // same with out.write( (byte[]) obj);
 }

employee.picture is byte[] of course, and it gets persisted later into database. so i guess something's wrong with my treatment of mediaOutput

add please also

<f:param value="#{fileUploadBean.timeStamp}" name="time"/>

as a child of mediaOutput
and

 public long getTimeStamp(){
 return System.currentTimeMillis();
 }

to your bean as it performed in demo.

still nothing!

interesting, i've tried the example from the demo site (the one with 2D graphics) and it works
