命名空间/操作名称没有映射的Action

Question

目前我正在使用Live struts2项目。该项目工作正常。但有时，我会得到一些意想不到的行为。

作为一个例子，我正在测试项目，一切正常。突然，我重复了相同的操作并得到了以下错误。

Struts Problem Report Struts has detected an unhandled exception: Messages: There is no Action mapped for namespace / and action name rfq. Stacktraces There is no Action mapped for namespace / and action name rfq. - [unknown location] com.opensymphony.xwork2.DefaultActionProxy.prepare(DefaultActionProxy.java:189) org.apache.struts2.impl.StrutsActionProxy.prepare(StrutsActionProxy.java:61) org.apache.struts2.impl.StrutsActionProxyFactory.createActionProxy(StrutsActionProxyFactory.java:39) com.opensymphony.xwork2.DefaultActionProxyFactory.createActionProxy(DefaultActionProxyFactory.java:58) org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:488) org.apache.struts2.dispatcher.ng.ExecuteOperations.executeAction(ExecuteOperations.java:77) org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter.doFilter(StrutsPrepareAndExecuteFilter.java:91) org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:861) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:606) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) java.lang.Thread.run(Unknown Source) You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set: struts.devMode=false in your WEB-INF/classes/struts.properties file.

我使用相同的操作再次测试，并且工作正常。

我对问题进行了研究，但解决方案是频繁出错，但这个错误很少和出乎意料地出现。

有没有人遇到过这种问题并解决了？

N.B：很抱歉，由于时间不够，我无法分享项目结构。任何帮助都会得到满足。
