Интеграция CKEditor со SmartGWT

Я попытался интегрировать CKEditor в приложение SmartGWT с помощью модуля gwt-ckeditor. Но я получаю сообщение об ошибке, когда пытаюсь отобразить приложение в режиме разработки:

Вот кусок моего кода:

public class CampaignMessageDesignPage extends Page {

    protected VLayout mainLayout;

    protected CKEditor ckEditor;

    @Override
    protected void prepareMainLayoutCanvasCandidate() {
        mainLayout = createOrGetVLayoutById(campaignMessageDesignPage_id);
        mainLayout.setWidth100();
        mainLayout.setHeight100();
        mainLayout.setDefaultLayoutAlign(Alignment.CENTER);

        Canvas cnvEditor = new Canvas("cnvEditor");
        CKConfig conf = new CKConfig(PRESET_TOOLBAR.FULL);
        ckEditor = new CKEditor(conf);
        conf.setBaseFloatZIndex(1000000);
        conf.setUseFormPanel(false);
        ckEditor.setHTML("");
        ckEditor.setSize("100%", "100%");
        cnvEditor.addChild(ckEditor);
        cnvEditor.setSize("50%", "50%");

        mainLayout.setMembers(cnvEditor);
    }

    @Override
    protected final Canvas getMainLayoutCanvasCandidate() {
        return this.mainLayout;
    }

    @Override
    protected void process(final SimpleBO param) {
        // TODO Auto-generated method stub
    }

}

Метод draw() вызывается в другом месте.

Есть ли у вас какие-либо идеи?

Изменить: я пробовал разные вещи. Я попытался добавить стандартные виджеты GWT в свой макет SmartGWT, и это сработало нормально, так что это действительно проблема, связанная с CKEditor.

Я также попытался создать содержимое на странице и получил другое сообщение об ошибке, надеюсь, более полезное:
