Problem with JSON object in qooxdoo

Question

When I'm sending AJAX query to my webApp, Qooxdoo cannot interpret the response correctly when server return response with header:

Content-Type: application/json; charset=utf-8

Here is sample code:

var req = new qx.io.remote.Request("http://localhost:8080/bm/login.json","POST","application/json");
req.setFormField('login',this.loginInput.getValue());
req.setFormField('password',this.passwordInput.getValue());

req.addListener("completed", function(response){
    var result = response.getContent();
    alert(result); // expected: object
    alert(result.status); // expected: 200
}, this);

req.send();

In this case alert(result) returns to me null (should be object).

Qooxdoo app and server app runs on http://localhost:8080/

If I change mime-type header to:

Content-Type: text/html; charset=utf-8

everything works correctly.

When I add to firefox addition named JSONView then alert(result); returns to me:

<doctype html="">
  <div id="json">
    <ul class="obj collapsible">
      <li>
        <span class="prop">session_id</span>
        :
        <span class="string">"e4cfcd8e91c567cce3767375dd3fd9d"</span>
      </li>
      <li>
        <span class="prop">status</span>
        :
        <span class="num">200</span>
      </li>
    </ul>
  </div>
</doctype>

but server response is:

{"session_id":"31446a34db6961a8d67e4e47c96cfb4","status":200}

So, I think that Qooxdoo use response modified by Firefox, not the pure code returned from serwer. In frameworks like jQuery I've had never any problems with that.

Is there any solution for this, or should I add jQuery framework and use jQuery ajax requests?

I have: Qooxdoo 1.2.1 and firefox 3.6.12 under Linux.

I've noticed that when I change method type form POST to GET and set form parameters to URL with req.setParameter(...) everything is ok. — tchudyk

as you already mentioned the switch from POST to GET is the solution.

Additionally, the setFormField method does internally switch to the IframeTransport implementation. So if you want to use the AJAX transport you should stick with the setParametermethod - as you already do.
