将CKEditor与SmartGWT集成

我尝试使用gwt CKEditor模块将CKEditor集成到SmartGWT应用程序中。但是，当我尝试在开发模式下显示应用程序时，出现了一个错误：

下面是我的一段代码：

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
    }

}

draw（）方法在别处调用

你知道吗

编辑： 我尝试了一些不同的东西。我尝试将标准GWT小部件添加到SmartGWT布局中，但效果很好，因此这确实是一个与CKEditor相关的问题

我还尝试在页面显示上创建内容，并获得另一条错误消息，希望更有用：

SmartGWT Extensions Google Code项目中有一个组件可以为您实现这一点：

实际上，这使用了旧版本的FCKEditor，不再维护了……您仍然应该看看这些代码，因为它是嵌入第三方JS小部件的一个工作示例。请注意，您报告的警告只是一个警告—它表示对draw（）进行了不必要的调用，但并不能解释您的问题。相反，您应该将代码与SmartGWT扩展示例进行比较，和/或使用Firebug之类的工具查看DOM，并尝试找出CKEditor不绘制的原因。我将对此进行研究。记录在案，我当前的（非工作代码）来自于可能是版本问题？您认为此代码是否仍应与当前版本的SmarGWT一起使用？我查看了SmartGWT扩展，显然，它不再维护，实际上无法与当前版本的SmartGWT一起使用。出于某种原因，缺少一段错误跟踪。我刚刚添加了它。事实上，我切换到了TinyMCE，它在SmartGWT中工作得更好。因为我没有得到任何答案，我理解这意味着GWTCKEditor库已经损坏，至少在最后的SmartGWT版本中是这样的？真遗憾。。。
