无法从 WicketStuff 找到资源 org.apache.wicket.mfu.delete：MultiFileUploadField.java

Question

我一直在尝试合并来自 wicketstuff.org 的 MultiFileUpload 示例，但找不到 org 的资源.apache.wicket.mfu.删除。原始代码可以在上面的链接中找到，我现在省略了我的代码，但如果有帮助的话可以包含它。对缺失包的调用发生在 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。我在下面的代码中从 org.apache.wicket.markup.html.IHeaderContributor 调用 renderHead() 方法。

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()");
        }
    }));

接下来是我对 MultiFileUploadField() 的调用，其中似乎导致问题的 renderHead() 方法所在。

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

最后这是堆栈跟踪：

根据错误消息，.properties 文件中没有为 multifileupload 字段的 delete 字符串定义字符串。

我想您需要在您的 Application.properties （一个与您的 Application 类同名的属性文件，但扩展名为 .properties）中定义这个文件，使用以下语法：

org.apache.wicket.mfu.delete=remove
