tomahawk-1.1.6 UploadedFile not working.

[le3000]

I follow the example in "Upload Files with JSF and MyFaces" from ONJava.com
to do the file upload. I am having problem on UploadedFile null pointer. 
The UploadedFile always return null. actually, the setter-setMyFile never
even get called.

Here is what I have in my jsp:
<[EMAIL PROTECTED] uri="http://java.sun.com/jsf/core"; prefix="f"%>
<[EMAIL PROTECTED] uri="http://java.sun.com/jsf/html"; prefix="h"%>
<%@ taglib uri="http://myfaces.apache.org/tomahawk"; prefix="t"%> 

<f:subview id="sendJobsub">
          <h:form id="sendJob" enctype="multipart/form-data">                   
             
          <h:messages globalOnly="true" styleClass="message"/>
          <h:panelGrid columns="3" border="0" cellspacing="5">
              <h:outputLabel for="myFileId" value="File: "/>
              <t:inputFileUpload id="myFileId" value="#{SendJobBean.myFile}"
storage="file" required="true"/>
        
              <h:outputLabel for="myParamId" value="Param: "/>
              <h:selectOneMenu id="myParamId" value="#{SendJobBean.myParam}" 
required="true">
                  <f:selectItem itemLabel="" itemValue=""/>
                  <f:selectItem itemLabel="MD5" itemValue="MD5"/>
                  <f:selectItem itemLabel="SHA-1" itemValue="SHA-1"/>
                  <f:selectItem itemLabel="SHA-256" itemValue="SHA-256"/>
                  <f:selectItem itemLabel="SHA-384" itemValue="SHA-384"/>
                  <f:selectItem itemLabel="SHA-512" itemValue="SHA-512"/>
              </h:selectOneMenu>
              <h:message for="myParamId"/>

              <h:outputText value=" "/>
              <h:commandButton value="Upload XML File"
action="#{SendJobBean.processXMLFile}"/>
              <h:outputText value=" "/>       
          </h:panelGrid>          
    </h:form>    
</f:subview>

Here is my web.xml:
   <filter>
        <filter-name>ExtensionsFilter</filter-name>
       
<filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>
        <init-param>                
                <param-name>uploadMaxFileSize</param-name>
                <param-value>100m</param-value>
        </init-param>
        <init-param>                
                <param-name>uploadThresholdSize</param-name>
                <param-value>100k</param-value>
        </init-param>  
    </filter>
    <filter-mapping>
                <filter-name>ExtensionsFilter</filter-name>
                <servlet-name>Faces Servlet</servlet-name>
        </filter-mapping>
        <filter-mapping>
                <filter-name>ExtensionsFilter</filter-name>
                <url-pattern>/*</url-pattern>
        </filter-mapping>

My bean is very simple:
........
private UploadedFile myFile;
........
public void setMyFile(UploadedFile myFile){
        System.out.println("setting uploaded file");
        this.myFile=myFile;
    }

    public UploadedFile getMyFile(){
        System.out.println("getting uploaded file");
        return this.myFile;
    }
    public void processXMLFile() throws Exception {
        String myResult="";
        try {
            MessageDigest md  = MessageDigest.getInstance(myParam);            
            InputStream in = new
BufferedInputStream(myFile.getInputStream());
            try {
                byte[] buffer = new byte[64 * 1024];
                int count;
                while ((count = in.read(buffer)) > 0)
                    md.update(buffer, 0, count);
            } finally {
                in.close();
            }
            byte hash[] = md.digest();
            StringBuffer buf = new StringBuffer();
            for (int i = 0; i < hash.length; i++) {
                int b = hash[i] & 0xFF;
                int c = (b >> 4) & 0xF;
                c = c < 10 ? '0' + c : 'A' + c - 10;
                buf.append((char) c);
                c = b & 0xF;
                c = c < 10 ? '0' + c : 'A' + c - 10;
                buf.append((char) c);
            }
            myResult = buf.toString();
            System.out.println(myResult);
        } catch (Exception x) {
            x.printStackTrace();
            FacesMessage message = new FacesMessage(
                FacesMessage.SEVERITY_FATAL,
                x.getClass().getName(), x.getMessage());
            FacesContext.getCurrentInstance().addMessage( null, message);       
     
        }
    }

It always always catch null pointer on UploadedFile, and the
UploadedFile(myFile) getter being call when I load that page, but the setter
never being called.

Please help. I've been struggling on this for days. :-(
