Module inheritance problem: Refused to display document because display forbidden by X-Frame-Options.

[Alexander Orlov]

I have two modules

Manager.gwt.xml

    <inherits name="dp.verp.planer.Planer"/>

    <entry-point class="dp.verp.manager.client.Main"/>

    <add-linker name="xsiframe"/>

which inherits Planer.gwt.xml but when I call the Manager module I get 

    Refused to display document because display forbidden by X-Frame-Options.

which is displayed in the Web Inspector console. Everything works fine when I omit the getI18nFacet() call. 

    @Override

    public void onModuleLoad() {

        final Widget app = binder.createAndBindUi(this);

        cookieInit();

        //getI18nFacet();

        RootPanel.get().add(app);

    }

    public void getI18nFacet() {

        final I18nFacetReqCtx ctx = PlanerUtils.RF.textpoolReqCtx();

        final Request<List<I18nFacetProxy>> req = ctx.getI18nFacet(

                Integer.valueOf(Cookies.getCookie("nativeLanguage"))

        );

        req.fire(new Receiver<List<I18nFacetProxy>>() {

            @Override

            public void onSuccess(List<I18nFacetProxy> response) {

                for (final I18nFacetProxy i18nFacet : response) {

                    Planer.property.i18nFacet.put(i18nFacet.getMacroName(), i18nFacet.getTranslation());

                }

            }

        });

    }

...the onMouduleLoad() code is located in dp.verp.manager.client.Main.

Solution: 

I haven't initialized the RequestFactory before calling getI18nFacet().
