将wicket从1.3.6迁移到1.4.0时哪些方法有所改变？

Question

我正在将wicket从1.3.6迁移到1.4.0.我通过getModel()和getModelObject()方法得到语法错误.它说它们是未定义的,因此它们阻止了应用程序的编译.我应该使用哪种方法代替它们？

这是我的代码的一部分:

@SuppressWarnings("unchecked")
public BreadCrumbTrail(String id, IModel model) {
    super(id, model);

    // Keep a count of the crumbs
    int count = 1;
    // Get the crumbs
    List<Crumb> crumbs = (List<Crumb>) getModelObject();
    // Create a repeating view to render the crumbs within
    RepeatingView repeating = new RepeatingView("crumbs");
    add(repeating);

    // Add each crumb
    for (final Crumb crumb : crumbs) {
        WebMarkupContainer item = new WebMarkupContainer(repeating
                .newChildId());
        repeating.add(item);

        // Create a link from the page held in the crumb
        @SuppressWarnings("serial")
        Link link = new Link("link", item.getModel()) {
            public void onClick() {
                setResponsePage(crumb.getPage());

            }
        };
        // Add a title/label to the link
        link.add(new Label("title", crumb.getTitle()));
        item.add(link);

        // Is this the last crumb?
        if (count == crumbs.size()) {
            // Don't add the normal separator
            item.add(new Label("separator", " "));
            // Disable the link as this is the current page
            link.setEnabled(false);
        } else {
            // Add the separator
            item.add(new Label("separator", " > "));
        }

        // Up the count of crumbs
        count++;
    }
}

使用getDefaultModelObject()替代

Wicket通常提供迁移指南:https: //cwiki.apache.org/WICKET/migrating-to-wicket-14.html#MigratingtoWicket1.4-Component.getModel%2528%2529andfriendsrenamedtogetDefaultModel%2528%2529andfriends

BTW:wicket 1.5也已经出局了
