Example 1 with IPageFactory

use of org.apache.wicket.IPageFactory in project midpoint by Evolveum.

the class MainMenuPanel method menuItemPerformed.

private void menuItemPerformed(MenuItem menu) {
    LOGGER.trace("menuItemPerformed: {}", menu);
    IPageFactory pFactory = Session.get().getPageFactory();
    WebPage page = pFactory.newPage(menu.getPageClass(), menu.getParams());
    if (!(page instanceof PageBase)) {
        setResponsePage(page);
        return;
    }
    PageBase pageBase = (PageBase) page;
    // IMPORTANT: we need to re-bundle the name to a new models
    // that will not be connected to the old page reference
    // otherwise the old page will somehow remain in the memory
    // I have no idea how it could do that and especially how
    // several old pages can remain in memory. But if the model
    // is not re-bundled here then the page size grows and never
    // falls.
    MainMenuItem mainMenuItem = getModelObject();
    String name = mainMenuItem.getNameModel().getObject();
    Breadcrumb bc = new Breadcrumb(new Model<>(name));
    bc.setIcon(new Model<>(mainMenuItem.getIconClass()));
    pageBase.addBreadcrumb(bc);
    List<MenuItem> items = mainMenuItem.getItems();
    if (!items.isEmpty() && mainMenuItem.isInsertDefaultBackBreadcrumb()) {
        MenuItem first = items.get(0);
        IModel<String> nameModel = first.getNameModel();
        BreadcrumbPageClass invisibleBc = new BreadcrumbPageClass(new Model<>(nameModel.getObject()), first.getPageClass(), first.getParams());
        invisibleBc.setVisible(false);
        pageBase.addBreadcrumb(invisibleBc);
    }
    setResponsePage(page);
