title: Play framework 2.0 Form.bindFromRequest().get() returns empty model
body: <p>I need to receive same POST data from a socket communication.</p>
  
  <p>This is the code that send the POST and receive the response, and seems to work correctly:</p>
  
  <pre><code>String data = "t=" + URLEncoder.encode("Title", "UTF-8") +
      "&amp;u=" + URLEncoder.encode("http://www.myurl.com", "UTF-8");
  
  URL url = new URL("http://localhost:9000/adserver");
  URLConnection conn = url.openConnection();
  conn.setDoOutput(true);
  OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
  wr.write(data);
  wr.flush();
  
  BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
  String output = "Data received\r\n", line;
  while ((line = rd.readLine()) != null) {
      output += line;
  }
  wr.close();
  rd.close();
  
  return ok(output);
  </code></pre>
  
  <p>This is the code that receive the POST:</p>
  
  <pre><code>Form&lt;AdRequest&gt; form = form(AdRequest.class).bindFromRequest();
  
  if(form.hasErrors()) {
      return badRequest("error");
  } else {
      AdRequest adr = form.get();
      return ok(adr.t + " - " + adr.u);
  }
  </code></pre>
  
  <p>The AdRequest model is defined in this way:</p>
  
  <pre><code>public class AdRequest {
      public String t;
      public String u;
  }
  </code></pre>
  
  <p>The form object receive the data because I can see them in debug, but the adr object returned by the get() method contains only null values:</p>
  
  <pre><code>adr = {
      t: null,
      u: null
  }
  </code></pre>
  
  <p>Instead, if I use this code to read the data it works correctly:</p>
  
  <pre><code>Map&lt;String, String[]&gt; asFormUrlEncoded = request().body().asFormUrlEncoded();
  return ok(asFormUrlEncoded.get("t")[0] + " - " + asFormUrlEncoded.get("u")[0]);
  </code></pre>
  
  <p>What I'm doing wrong?
  Is it a Play Framework bug?</p>
  
  <p>Thanks.</p>
