PrimeFaces错误StateHelper

Question

我该怎么办才能解决这个错误？ 当我使用撇号运行我的Web应用程序时，会出现此错误，该应用程序可以识别库和标签，但是会发生某些情况。 如果可以解决，请帮助我。 这是我的错误java.lang.NoSuchMethodError：org.primefaces.component.spinner.Spinner.getStateHelper（）Ljavax / faces / component / StateHelper; 在org.primefaces.component.spinner.Spinner.getStepFactor（Spinner.java:68）在org.primefaces.component.spinner.SpinnerRenderer.calculateFractionDigits（SpinnerRenderer.java:72）在org.primefaces.component.spinner.SpinnerRenderer。 （SpinnerRenderer.java:52）在org.primefaces.component.spinner.SpinnerRenderer.encodeEnd（SpinnerRenderer.java:45）在javax.faces.component.UIComponentBase.encodeEnd（UIComponentBase.java:649）在javax.faces.component。 org org.apache.myfaces.application.jsp.JspViewHandlerImpl.actuallyRenderView（JspViewHandlerImpl.java:427）上的javax.faces.component.UIComponent.encodeAll（UIComponent.java:257）上的UIComponent.encodeAll（UIComponent.java:261） org.apache.myfaces.lifecycle.RenderResponseExecutor.execute（RenderResponseExecutor.java:41）上的.apache.myfaces.application.jsp.JspViewHandlerImpl.renderView（JspViewHandlerImpl.java:383）at org.apache.myfaces.lifecycle.LifecycleImpl.r （LifecycleImpl.java:140）在org.apache.myfaces.custom.ppr.PPRLifecycleWrapper.rende org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:290）的org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:290）的javax.faces.webapp.FacesServlet.service（FacesServlet.java:187）的r（PPRLifecycleWrapper.java:84） org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter（ExtensionsFilter.java:341）的org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java的.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206） ：235），位于org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:233），位于org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:233）的org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206）。 org上org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java:127）的org.apache.catalina.valves.ErrorReportValve.invoke（ErrorReportValve.java:102）的StandardContextValve.invoke（StandardContextValve.java:191） .apache.catalina.core.StandardEngineValve.invoke（StandardEngineValve.java:109）在或 g.apache.catalina.connector.CoyoteAdapter.service（CoyoteAdapter.java:298）位于org.apache.coyote.http11.Http11AprProcessor.process（Http11AprProcessor.java:861）位于org.apache.coyote.http11.Http11AprProtocol $ Http11ConnectionHandler。 org.apache.tomcat.util.net.AprEndpoint $ Worker.run（AprEndpoint.java:1584）处的进程（Http11AprProtocol.java:579）在java.lang.Thread.run（Thread.java:619）

        <description>
        A very common problem in configuring MyFaces-web-applications
        is that the Extensions-Filter is not configured at all
        or improperly configured. This parameter will check for a properly
        configured Extensions-Filter if it is needed by the web-app.
        In most cases this check will work just fine, there might be cases
        where an internal forward will bypass the Extensions-Filter and the check
        will not work. If this is the case, you can disable the check by setting
        this parameter to false.

我正在使用primefaces 2.0.0 Rc

Answer 1

我假设primefaces和JSF之间的版本不匹配。 对于Primefaces 2.0，我认为您需要JSF 2.0
