Question

I am trying to create a modal window for my application, but unfortunately I am unable to do so.

I have a page that extends WebPage and I have added a panel that extends Panel to it. The page and panel are written separately; that is, in panel.java and page.java. Now, I have added a modal window to the panel with the help of this Wicket Examples example (source). But when the page renders, I am seeing — by inspecting element of that page — that the div with wicket:id of “modal1” has attribute script="display: none". I don’t know what to do. Any information will be very helpful to me.

One more thing: are

return new ModalContent1Page(ModalWindowPage.this.getPageReference(), modal1);

and

return new ModalContent1Page(ModalWindowPage.this, modal1);

the same?

Edit:

The problem is solved. Actually when I asked the question I did not have the code then. I was following the tutorial of RoseIndia, but I was unsuccessful and as I am using wicket 1.3.1 the PageReference class is not available there. So I solve it as:

    final ModalWindow modalWindow;
    add(modalWindow = new ModalWindow("modalVideo"));

    modalWindow.setCookieName("modal-video");
    modalWindow.setCssClassName(ModalWindow.CSS_CLASS_GRAY);
    modalWindow.setResizable(false);
    modalWindow.setInitialHeight(215);
    modalWindow.setInitialWidth(215);
    modalWindow.setHeightUnit("px");        

    modalWindow.setPageCreator(new ModalWindow.PageCreator() {
        public Page createPage() {
            return new PlayVideo(ItemViewPanel.this.getPage(), modalWindow, itemId);
        }
    });

    AjaxLink showModalLink;
    add(showModalLink = new AjaxLink("showModal") {
        @Override
        public void onClick(AjaxRequestTarget target) {
                    modalWindow.show(target);
        }
    });

Thank you.

To answer your second question: no, those two lines of code are not the same. ModalWindowPage.this is the page itself, so its type is ModalWindowPage. getPageReference(), on the other hand, returns a PageReference, which is not in the same hierarchy.
