cor.ted中的一个desgined Form在theme.res文件中

Question

我没有更新这个themes.res（使用CN设计师一段时间）突然1天后我在我的代码中做了一些更新并发送了一个Android版本进行重建，我发现其中一个表单不起作用..当表单显示时，应用程序通过

在空对象引用上的

'java.lang.String com.codename1.q.r.be（）'。

经过调查，我发现UI Designer能够打开theme.res文件，但无法显示特定表单“Report”。

我在命令行中重新运行设计器，以便通过UI Designer查看任何错误，它是：

~]$ java -jar ~/.codenameone/designer_1.jar

有人请建议发生什么事？

Answer 1

要解决此问题，您可以删除并重新创建该表单。假设你找到一种方法来一致地重现这个，我想知道它是什么。

在将项目复制到一边之前，打开该项目。假设您正在使用NetBeans，请转到项目属性，然后选择将旧的GUI构建器项目转换为Codename One部分下项目属性中的新GUI构建器项目的选项。

完成后，转到视图的files部分并查看项目。打开res/guibuilder，找到与此表单匹配的.gui文件。在其中查看您应该看到一个具有“有问题”类型值的组件...如果没有，请编辑您的问题并将.gui文件的XML放在那里。
