我正在使用intelli Idea，我已经安装了codenameone插件。从早上起它工作得很好。现在，我正在尝试使用 gui builder 打开我的表单，但它给了我以下异常。它也显示禁用插件，我尝试过相同的。我已经卸载并重新安装了插件，但在尝试在 GUI Builder中打开表单时仍然显示相同的错误。 任何帮助表示感谢

答案 0 :(得分：0)
我们将在下次更新时修复错误。当您尝试打开常规Java文件或不是GUI构建器文件的任何其他文件时，会发生错误。
确保从模板创建GUI构建器文件。这会产生另一个影子＆＃34; .gui目录层次结构下具有res/guibuilder扩展名的XML文件。
