我已经使用 uiBinder 创建了一个自定义小部件，我想将其包含在另一个 uiBinder 布局中。

我试过了：

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
    xmlns:g="urn:import:com.google.gwt.user.client.ui" xmlns:my="urn:import:net.sti.learning.client.view">
    <ui:style>

    </ui:style>
    <g:HTMLPanel>
        <g:VerticalPanel width="800px">
            <my:PostView ui:field="postView"/>
        </g:VerticalPanel>
    </g:HTMLPanel>
</ui:UiBinder>

但是 gwt 设计师抱怨说：

[错误] 无法通过延迟绑定创建“net.sti.learning.client.view.PostView”的实例

编辑：

这是 PostWidget.ui.xml：

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
    xmlns:g="urn:import:com.google.gwt.user.client.ui">
    <ui:style>

    </ui:style>
    <g:HTMLPanel width="600px" height="">
        <g:DecoratorPanel width="600px" height="">
            <g:VerticalPanel width="600px" height="">
                <g:HorizontalPanel width="600px" height="30px" verticalAlignment="ALIGN_MIDDLE">
                    <g:Label text="This is the post title" width="500px" height="30px" horizontalAlignment="ALIGN_LEFT" ui:field="postTitle"/>
                    <g:SimplePanel width="100px" height="30px" styleName="dateDiv">
                        <g:DateLabel width="100%" height="100%" horizontalAlignment="ALIGN_RIGHT" ui:field="postDate"/>
                    </g:SimplePanel>
                </g:HorizontalPanel>
                <g:SimplePanel width="600px" height="auto" styleName="postContent">
                    <g:HTML wordWrap="true" width="100%" height="100%" ui:field="postContent">Lorem ipsum dolor sit amet, cursus sapien in vivamus, et ligula luctus eu ut et vitae, mauris ultrices nec.

                    <g:InlineLabel text="Author" width="100%" height="100%" horizontalAlignment="ALIGN_CENTER" ui:field="postAuthor"/>
                </g:SimplePanel>
            </g:VerticalPanel>
        </g:DecoratorPanel>
    </g:HTMLPanel>
</ui:UiBinder>

及其相关的java文件：

package net.sti.learning.client.view;

import java.util.Date;

import com.google.gwt.core.client.GWT;
import com.google.gwt.safehtml.shared.SafeHtml;
import com.google.gwt.safehtml.shared.SafeHtmlBuilder;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.Widget;
import com.google.gwt.uibinder.client.UiField;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.DateLabel;
import com.google.gwt.user.client.ui.HTML;
import com.google.gwt.user.client.ui.InlineLabel;

public class PostWidget extends Composite {

    private static PostWidgetUiBinder uiBinder = GWT
            .create(PostWidgetUiBinder.class);
    @UiField Label postTitle;
    @UiField DateLabel postDate;
    @UiField HTML postContent;
    @UiField InlineLabel postAuthor;

    interface PostWidgetUiBinder extends UiBinder<Widget, PostWidget> {
    }

    public PostWidget() {
        initWidget(uiBinder.createAndBindUi(this));
    }

    public void setData(String title, Date pubDate, String content, String author){
        this.postTitle.setText(title);
        this.postDate.setValue(pubDate);
        SafeHtmlBuilder safeHtmlBuilder = new SafeHtmlBuilder();
        safeHtmlBuilder.appendEscapedLines(content);
        SafeHtml safeContent = safeHtmlBuilder.toSafeHtml();
        this.postContent.setHTML(safeContent);
        this.postAuthor.setText(author);
    }

}

以前有人做过吗？

谢谢！
