How to defeat browser dialog popup when calling Wicket setResponsePage() from modal window?

How to defeat IE and Firefox dialog popup when trying to setResponsePage() from a wicket modalWindow per below. Dialog popup demands an answer to: "This page is asking you to confirm that you want to leave - data you have entered may not be saved."

    AjaxLink signInContainer = new AjaxLink("signInContainer") {
        @Override
        public void onClick(AjaxRequestTarget target) {
            target.appendJavascript("Wicket.Window.unloadConfirmation = false;");

            modalWindow.close(target);
            setResponsePage(SignInPage.class);
            modalWindow.close(target);
        }
    };

In wicket 6.x and above you can simply set showUnloadConfirmation to false:

final ModalWindow modalWindow = new ModalWindow("modalWindow");
modalWindow.showUnloadConfirmation(false);

EDIT: This is a hack, use the alternative described in my other answer.

Try this:

public void onClick(AjaxRequestTarget target) {
    modal.close(target);
    CharSequence url = urlFor(HomePage.class, new PageParameters("gone=true"));
    target.appendJavascript("window.location='" + url + "';");
}

target.appendJavascript("Wicket.Window.unloadConfirmation = false;"); doesn't work because it must run before modal.show(target);.

You could either prepend, instead of append, the script, when opening the window:

add(new AjaxLink<Void>("show") {
    @Override
    public void onClick(AjaxRequestTarget target) {
        target.prependJavascript("Wicket.Window.unloadConfirmation = false;");
        modal.show(target);
    }
});

or add a behavior, to execute it on onload:

modal.add(new AbstractBehavior() {
    @Override
    public void renderHead(IHeaderResponse response) {
        response.renderOnLoadJavascript("Wicket.Window.unloadConfirmation = false;");
    }
});

But, it must be called before opening the modal window, not when navigating away from the page (setResponsePage()).

I believe setResponsePage() should be accompanied by some other methods to behave properly. For example, I often include setRedirect(true) when using this technique. I'm not sure what all is going on behind the scenes there, but perhaps try that.
