我使用一个远程命令按钮来执行一个bean级别的方法。但我的命令按钮不起作用

我在下面附上我的代码：

请检查我的远程命令不起作用的原因。

在

remoteCommand

上使用

process=“@this”

和

partialSubmit=“true”

究竟什么是“不起作用”？您甚至没有在代码中的任何地方调用

doAlert

。那么您希望发生什么呢？另外，如果您的bean名称可能错误，方法名称/签名可能错误（因此请将一个最小但完全有效的bean发布到），您可能有嵌套表单（来自模板），那么请创建一个简化的示例…@user1983983我正在调用rc（）；在我的doAlert方法和doAlertMethod中applet@Kukeltje我正在更新我的问题。请检查更新是否如预期那样发出警报，但未记录值为且按钮未更新？
