GridUtil displays nothing when i set the renderer

Hello,

I want to create a customelized grid with GridUtil to be able to add/Modify/Delete some information, see the example, i don't understand how to use it, because it displays nothing when i call setColumnRenderes();

private Grid genGrid() {
        // init Grid
        final Grid grid = new Grid();
        grid.setSizeFull();

        // init Container
        List<Template> templates = new ArrayList<Template>();
        templates.add(new Template(1, "template 1 ", "user1"));
        templates.add(new Template(2, "template 2 ", "user1"));
        templates.add(new Template(3, "template 3 ", "user2"));
        BeanItemContainer<Template> container = new BeanItemContainer<Template>(Template.class, templates);
        grid.setContainerDataSource(container);
        grid.setColumnOrder("id", "user", "name");

        setColumnRenderes(grid);

        initFilter(grid);
//        initFooterRow(grid, container);
//        initExtraHeaderRow(grid);
//
        initColumnAlignments(grid);
        return grid;
    }
    
    private void setColumnRenderes(final Grid grid) {
        [b]grid.getColumn("id")
        .setRenderer(new EditDeleteButtonValueRenderer(new EditDeleteButtonClickListener() {

            @Override
            public void onEdit(final RendererClickEvent event) {
                Notification.show(event.getItemId()
                        .toString() + " want's to get edited", Type.HUMANIZED_MESSAGE);
            }

            @Override
            public void onDelete(final com.vaadin.ui.renderers.ClickableRenderer.RendererClickEvent event) {
                Notification.show(event.getItemId()
                        .toString() + " want's to get delete", Type.WARNING_MESSAGE);
            };

        }))
        .setWidth(150);[/b]
    }

In MainUI:

CustomerTableColumnsSelectorComponent filterComponent = new CustomerTableColumnsSelectorComponent();
        layout.addComponent(filterComponent);

Should i add a file in webapp folder?
and should i add in main UI class something like that:

@WebServlet(
            value = "/*",
            asyncSupported = true)
    @VaadinServletConfiguration(
            productionMode = false,
            ui = DemoUI.class,
            widgetset = "org.vaadin.gridutil.demo.DemoWidgetSet")
    public static class Servlet extends VaadinServlet {
    }

I think may be it's related to the widget, because I cannot compile this widget, this is my pom:

        </dependency>

Then i created the file src\main\java\com\ui\DemoWidgetSet.gwt.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.5.1//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.5.1/distro-source/core/src/gwt-module.dtd">
<module>

    <set-configuration-property name="devModeRedirectEnabled" value="true" />


    <inherits name="com.vaadin.DefaultWidgetSet" />

    <inherits name="org.vaadin.gridutil.WidgetSet" />
</module>

When i run mvn package, no error and no folder widget created in "src\main\webapp\VAADIN".

Someone knows this problem, please?
 

Sorry i a dummy in Vaadin.
I have the same or similar problem.
Have you a solution?

Thank's

I found the problem, it's related to my POM, but finally i chose the table, because it's more easy to control.
