GWT编辑器bug？,gwt,Gwt,这是我的开发环境： ubuntu 12.04 LTS Eclipse版本：3.7.2（Indigo） Eclipse3.7的谷歌插件 谷歌网络工具包2.4.0 GWT Designer核心2.5.0 GWT Designer GPE 2.5.0 WindowBuilder核心1.3.0 WindowBuilder CSS支持1.2.0 WindowBuilder XML核心1.3.0 我用“appengineconnectedandroid项目”创建了一个gwt/appengine项目，并做

这是我的开发环境：

  • ubuntu 12.04 LTS
  • Eclipse版本：3.7.2（Indigo）
  • Eclipse3.7的谷歌插件
  • 谷歌网络工具包2.4.0
  • GWT Designer核心2.5.0
  • GWT Designer GPE 2.5.0
  • WindowBuilder核心1.3.0
  • WindowBuilder CSS支持1.2.0
  • WindowBuilder XML核心1.3.0
我用“appengineconnectedandroid项目”创建了一个gwt/appengine项目，并做了很多修改（只是重构了几个名称）

当我单击我的“ui.xml”gwt文件时，我可以在Eclipse编辑器窗口的“xml源”选项卡中显示它

但是，当我单击“设计”选项卡时，出现以下错误：

Internal Error

encountered unexpected internal error.

This could be caused by a bug or by a misconfiguration issue, conflict, partial update, etc.
