    Problem with rich fileUpload

    Pra Vardhan Newbie

      I am trying to replicate the file upload example in my project
      http://livedemo.exadel.com/richfaces-demo/richfaces/fileUpload.jsf?tab=usage&cid=1058914

      But the uploaded Files info panel doesn't list the uploaded files.
      xhtml page:
      <h:form>
      <h:panelGrid columns="2" columnClasses="top,top">
      <rich:fileUpload fileUploadListener="#{fileUploadBean.listener}"
      maxFilesQuantity="#{fileUploadBean.uploadsAvailable}"
      id="upload"
      immediateUpload="#{fileUploadBean.autoUpload}"
      acceptedTypes="jpg, gif, png, bmp" allowFlash="#{fileUploadBean.useFlash}">
      <a4j:support event="onuploadcomplete" reRender="info" />
      </rich:fileUpload>
      <h:panelGroup id="info">
      <rich:panel bodyClass="info">
      <f:facet name="header">
      <h:outputText value="Uploaded Files Info" />
      </f:facet>
      <h:outputText value="No files currently uploaded"
      rendered="#{fileUploadBean.size==0}" />
      <rich:dataGrid columns="1" value="#{fileUploadBean.files}"
      var="file" rowKeyVar="row">
      <rich:panel bodyClass="rich-laguna-panel-no-header">
      <h:panelGrid columns="2">
      <a4j:mediaOutput element="img" mimeType="#{file.mime}"
      createContent="#{fileUploadBean.paint}" value="#{row}"
      style="width:100px; height:100px;" cacheable="false">
      <f:param value="#{fileUploadBean.timeStamp}" name="time"/>
      </a4j:mediaOutput>
      <h:panelGrid columns="2">
      <h:outputText value="File Name:" />
      <h:outputText value="#{file.name}" />
      <h:outputText value="File Length(bytes):" />
      <h:outputText value="#{file.length}" />
      </h:panelGrid>
      </h:panelGrid>
      </rich:panel>
      </rich:dataGrid>
      </rich:panel>
      <rich:spacer height="3"/>

      <a4j:commandButton action="#{fileUploadBean.clearUploadData}"
      reRender="info, upload" value="Clear Uploaded Data"
      rendered="#{fileUploadBean.size>0}" />
      </h:panelGroup>
      </h:panelGrid>
      </h:form>

      }

      public void setUseFlash(boolean useFlash) {
      this.useFlash = useFlash;
      }

      }

      File.java

      package com.calonex.util.fileUpload;
      public class File {
      private String Name;

      private long length;

      public void setData(byte[] data) {
      this.data = data;
      }
      public String getName() {

      }
      public void setName(String name) {
      Name = name;
      int extDot = name.lastIndexOf('.');
      if(extDot > 0){
      String extension = name.substring(extDot +1);
      if("bmp".equals(extension)){
      mime="image/bmp";
      } else if("jpg".equals(extension)){
      mime="image/jpeg";
      } else if("gif".equals(extension)){
      mime="image/gif";
      } else if("png".equals(extension)){
      mime="image/png";
      } else {

      }
      public long getLength() {
      return length;
      }
      public void setLength(long length) {
      this.length = length;
      }

      public String getMime(){
      return mime;
      }

      }

      Any ideas please!!!

      Thanks in advance.
