Codenameone插件给出空指针异常

Question

我正在使用智能理念，我已经安装了codenameone插件。自上午以来它运行良好。现在我试图用gui builder打开我的表单，但它给了我下面的例外。此外，它显示禁用插件，我已经尝试相同。我已经卸载并重新安装了插件，但仍尝试打开GUI Builder时显示相同的错误。 任何帮助表示赞赏感谢

我们将与下一个更新修复错误。当您尝试打开常规Java文件或任何其他不是GUI构建器文件的文件时，会发生错误。

确保从模板创建GUI生成器文件。这会在res/guibuilder目录层次结构下创建另一个带有.gui扩展名的“影子”XML文件。
