无法找到来自WicketStuff的资源org.apache.wicket.mfu.delete：MultiFileUploadField.java

我一直试图从wicketstuff.org合并MultiFileUpload示例，但无法找到org.apache.wicket.mfu.delete的资源。原始代码可以在上面的链接找到，我现在已经省略了我的代码，但如果它有帮助，可以包含它。对丢失的包的调用发生在org.apache.wicket.markup.html.form.upload.MultiFileUploadField.java的renderHead（）方法中，该方法是只读的。我正在使用wicket-1.3.1.jar。我在下面的代码中调用org.apache.wicket.markup.html.IHeaderContributor中的renderHead（）方法。无法找到来自WicketStuff的资源org.apache.wicket.mfu.delete：MultiFileUploadField.java

任何帮助将不胜感激。

add(new HeaderContributor(new IHeaderContributor() { 
     @Override 
     public void renderHead(IHeaderResponse response) { 
      response.renderOnLoadJavascript("document.getElementById('" + summaryField.getMarkupId() + "').focus()"); 
     } 
    }));

和明年是我的电话，以MultiFileUploadField（）式中，似乎是产生这些问题的renderHead（）方法所在。

add(new MultiFileUploadField("fileInput", new PropertyModel(this, "uploads"), 5));

最后是这样的堆栈跟踪：
