Problem with GWT Image Upload in my Touchkit app

Hi, I'm developing a mobile app using TouchKit that allows the user to take pictures with his mobile, but I can't make it work. Firstly, when I include the GWT Image Upload addon to WEB-INF/lib folder and then I try to use the ImageUpload component I get this message in line 9: "The type org.vectomatic.file.FileUploadExt cannot be resolved. It is indirectly referenced from required .class files".
 

final ImageUpload fileUpload = new ImageUpload();
        fileUpload.setCapture(true);

        // Normalize the orientation and make size suitable for
        // sending to server
        EXIFOrientationNormalizer normalizer = new EXIFOrientationNormalizer();
        normalizer.setMaxWidth(1024);
        normalizer.setMaxHeight(1024);
[color=#FF0000][b]        fileUpload.addImageManipulator(normalizer);[/b][/color]
        fileUpload.addImageLoadedHandler(new ImageLoadedHandler() {
            @Override
            public void onImageLoaded(ImageLoadedEvent event) {
                // Store the image data as encoded URL
                setImage(event.getImageData().getDataURL());
            }
        });
            

        // Reduce the size further for displaying a thumbnail
        ImageTransformer thumbGenerator = new ImageTransformer();
        thumbGenerator.setImageDataSource(fileUpload);
        thumbGenerator.setMaxWidth(75);
        thumbGenerator.setMaxHeight(75);
        thumbGenerator.addImageLoadedHandler(new ImageLoadedHandler() {
           @Override
           public void onImageLoaded(ImageLoadedEvent event) {
               // Store the thumbnail image data as encoded URL
//               setThumbnail(event.getImageData().getDataURL());
           }
        });
        
        Button image_Button = new Button();
        image_Button.addClickListener(new ClickListener(){
            @Override
            public void buttonClick(ClickEvent event) {
                // TODO Auto-generated method stub
                fileUpload.click();
            }
        });

If I download the GWT-File libraries and add them to my lib the message dissapears but when I run the application I get the "Widgetset does not contain implementation for ImageUpload..." message.

Secondly, if I include the TouchKit addon and the GWT Image upload addon in the ivy.xml file and not in the WEB-INF/lib folder I get a different error when I run the application: "com.vaadin.server.ServiceException: java.lang.NoClassDefFoundError: com/google/gwt/user/client/ui/HasName"

Does anybody know what's going on here? Any help will be appreciated,
Thanks in advance,
Matías
