java - 获取 Wicket.Event 对于 wicketAjaxGet() 是未定义的

Question

我正在尝试让用户通过 javascript sdk 登录到 facebook。 auth.login 的代码是:

Label loginEvent = new Label("loginEvent", new AbstractReadOnlyModel<String>() {
    public String getObject() {
        return "FB.Event.subscribe('auth.login',function(response) " +
        "{" +
        "alert('Finalmente, logado!');" +
        "var wcall = wicketAjaxGet('" + loginBehavior.getCallbackUrl() +
        "&fbid='+ response.authResponse.userID +'" +
        "&accessToken='+ response.authResponse.accessToken +'" +
        "',function() { }, function() { });" +
        "alert('Chamou o behavior!');" +
        "});";
    }
});

loginEvent.setEscapeModelStrings(false);
loginEvent.setOutputMarkupId(true);
add(loginEvent);

标签的 html 副本是:

<script wicket:id="loginEvent"></script>

当我登录 facebook 时，只显示第一个警报。我永远无法调用 wicketAjaxGet()。 Firebug 给了我这两个错误，Firefox 编译了这些脚本标签(wicket-event 返回不可读):

Wicket.Event is undefined
[Break On This Error]
Wicket.Browser is undefined
[Break On This Error]   
<script type="text/javascript" src="wicket/resource/org.apache.wicket.markup.html.WicketEventReference/wicket-event-ver-1327971835000.js"></script>
<script type="text/javascript" src="wicket/resource/org.apache.wicket.ajax.WicketAjaxReference/wicket-ajax-ver-1327971835000.js"></script>
<script type="text/javascript" src="wicket/resource/org.apache.wicket.ajax.AbstractDefaultAjaxBehavior/wicket-ajax-debug-ver-1327971835000.js"></script>

还有一个用于 facebook 的 wicketstuff 库。 https://github.com/wicketstuff/core/wiki/Facebook
