ironAjax setHeaders not work

[fizzi]

JSONObject openAmUser = new JSONObject(); openAmUser.put("X-OpenAM-Username",new JSONString("xxxxxx")); openAmUser.put("X-OpenAM-Password",new JSONString("xxxxxx")); openAmUser.put("x-requested-with",new JSONString("XMLHttpRequest"));

    openAmAjax.setHeaders(openAmUser.getJavaScriptObject());
    openAmAjax.setContentType("application/json");
    openAmAjax.generateRequest();

It's not a problem on gwt-polymer-elements, but in the way iron-ajax checks whether a value is a javascript Object.

Since GWT creates new objects in the sandboxed $wnd iframe via the JavaScriptObject.createObject() method, those objects are not instanceof Object in the application window.

As a workaround, create your headers using any of these ways:

  @JsMethod(namespace = JsPackage.GLOBAL, name = "Object")
  static native JavaScriptObject createObject();

  static native JavaScriptObject createObject() /*-{
    return $wnd.Object();
  }-*/;

And set the headers in this way:

   JavaScriptObject openAmUser = createObject();
   Polymer.property(openAmUser, "X-OpenAM-Username", "xxxxxx");
   Polymer.property(openAmUser, "X-OpenAM-Password", "xxxxxx");
   Polymer.property(openAmUser, "x-requested-with", "XMLHttpRequest");

 ajax.setHeaders(openAmUser);
