File upload problem - setFile( ) never called, please help!

Hi all,

I'm having a problem trying to get file upload to work.

        <h:form id="form1" name="form1" enctype="multipart/form-data" >
            <h:outputText value="Please give me an image"/>
            <t:inputFileUpload id="fileupload"
                               accept="image/*"
                               value="#{ui.someUser.file}"
                               storage="file"
                               required="true"/>
            <h:commandButton value="Upload Now!" action="" />
        </h:form>

My bean effectively has this in it:

import org.apache.myfaces.custom.fileupload.UploadedFile;
:
:
public class MyBean
{
    public void fileUploaded(ValueChangeEvent event)
    {
        UploadedFile file = (UploadedFile)event.getNewValue();
        if (file != null)
        {
            FacesContext context = FacesContext.getCurrentInstance();
            FacesMessage message = new FacesMessage("Successfully uploaded file " + file.getName() + " (" + file.getSize() + " bytes)");
            context.addMessage(event.getComponent().getClientId(context), message);
            // Here's where we could call file.getInputStream()
        }
        else
        {
            System.out.println("fileUploaded called with no file");
        }
    }

    public UploadedFile getFile()
    {
        return _file;
    }

    public void setFile(UploadedFile file)
    {
        // never called!
        _file = file;
    }

    public String doUpload()
    {
        UploadedFile file = getFile();
        // ... and process it in some way
        return (file != null ? file.getName() : "nullo");
    }

    private UploadedFile _file;
}

Please help!

Regards, Murray

================================================
extra notes:

1) I am using Facelets + Myfaces + Tomahawk + ADF faces.

2) For a start I get a _javascript_ error on submit because clear_form1(); does not exist not sure why it is missing.
The following html was generated:
<input id="form1:_id6" name="form1:_id6" type="submit" value="Upload Now!" >

3) My web.xml
    <filter>
        <filter-name>MyFacesExtensionsFilter</filter-name>
        <filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>
        <init-param>
            <param-name>maxFileSize</param-name>
            <param-value>20m</param-value>
            <description>Set the size limit for uploaded files.
                Format: 10 - 10 bytes
                        10k - 10 KB
                        10m - 10 MB
                        1g - 1 GB
            </description>
        </init-param>
    </filter>

    
    <filter-mapping>
        <filter-name>MyFacesExtensionsFilter</filter-name>
        <servlet-name>FacesServlet</servlet-name>
    </filter-mapping>

    
    <filter-mapping>
        <filter-name>MyFacesExtensionsFilter</filter-name>
        <url-pattern>/faces/myFacesExtensionResource/*</url-pattern>
    </filter-mapping>

4) ADF faces file upload exhibits the same behaviour.

5) The file is definitely attempting to be uploaded because if I give a really big file I get a SizeLimitExceededException.
