我尝试创建一个调试按钮，如下所示，参考底部的链接#3，我已经编译并配置了核心数据库中的按钮并配置了 Commands.config，但是当我单击时，我在主数据库上收到错误消息功能区和 sitecore 管理客户端已重新启动。我没有得到错误消息指向的内容..！
功能区按钮屏幕
错误消息文本
控制“系统”在表单上不存在。在 Sitecore.Shell.Framework.Commands.CommandManager.GetMethodCommand(String command) 在 Sitecore.Shell.Framework.Commands.CommandManager.GetDispatchCommand(String command) 在 Sitecore.Web.UI.Sheer.ClientPage.Dispatch(String command) 在 Sitecore .Web.UI.Sheer.ClientPage.RaiseEvent() 在 Sitecore.Web.UI.Sheer.ClientPage.OnPreRender(EventArgs e)
错误信息屏幕
底部提到的链接#2的另一件事似乎不包含 John 在此处的博客文章中所说的“资源部分中可用的原型 zip” .. 任何人都可以看到如果我没记错吗？
