使用Wicket AJAX-ically上传文件

我想在Wicket中使用AJAX上传文件。在我看来，Wicket不支持这个功能。可能吗？使用Wicket AJAX-ically上传文件

查看上传Wicket示例的源代码：http://www.wicketstuff.org/wicket13/upload/single。它有标准和ajax版本的例子。

它只是ajax进度条，并不完全ajax – JGC 2009-08-05 05:19:55

这种方法适用于完整的Ajax检票应用程序。对不起，这是斯卡拉语法，但应该是很容易转移回Java语法：

import java.io.File 
import org.apache.wicket.markup.html.form.upload.FileUploadField 
import org.apache.wicket.markup.html.form.Form 
import org.apache.wicket.markup.html.WebPage 
import org.apache.wicket.ajax.markup.html.form.AjaxSubmitLink 
import org.apache.wicket.ajax.AjaxRequestTarget 

class TestPage extends WebPage { 
    val uploadForm = new Form("form") 
    val fileField = new FileUploadField("file") 

    uploadForm.add(fileField) 
    add(form) 

    add(new AjaxSubmitLink("submit", uploadForm) { 
     def onSubmit(target: AjaxRequestTarget, form: Form[_]) { 
      val upload = fileField.getFileUpload 
      if (upload != null) { 
       val file: File = upload.writeToTempFile 
      } 
     } 
    }) 
}

HTML：

<!DOCTYPE html> 
<html xmlns="http://www.w3.org/1999/xhtml" 
     xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd"> 
<body> 

<form wicket:id="form"> 
    <input wicket:id="file" type="file"/> 
</form> 
<button wicket:id="submit">Upload</button> 

</body> 
</html>

为更新到一个老问题，现在看来，这是可能的现在：
