我能做些什麼來解決這個錯誤？當我使用primefaces運行我的web應用程序時，會發生此錯誤，應用程序會識別庫和標籤，但發生了一些情況。如果你能解決，請幫助我。 這是我的錯誤 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.encodeScript在（SpinnerRenderer.java:52） 在org.primefaces.component.spinner.SpinnerRenderer.encodeEnd（SpinnerRenderer.java:45） 在javax.faces.component.UIComponentBase.encodeEnd（UIComponentBase.java:649） javax.faces.component.UIComponent.encodeAll（UIComponent.java:261） at javax.faces.component.UIComponent.encodeAll（UIComponent.java:257） at org.apache.myfaces.application.jsp.JspViewHandlerImpl.actuallyRenderView（ JspViewHandlerImpl.java:427） at org.apache.myfaces.application.jsp.J spViewHandlerImpl.renderView（JspViewHandlerImpl.java:383） 在org.apache.myfaces.lifecycle.RenderResponseExecutor.execute（RenderResponseExecutor.java:41） 在org.apache.myfaces.lifecycle.LifecycleImpl.render（LifecycleImpl.java:140） at org.apache.catalina.core上的javax.faces.webapp.FacesServlet.service（FacesServlet.java:187） org.apache.myfaces.custom.ppr.PPRLifecycleWrapper.render（PPRLifecycleWrapper.java:84） 。 ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:290） at org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206） at org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter（ExtensionsFilter.java： 341） at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（Applicat ionFilterChain.java:235） 在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206） 在org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:233） 在有機apache.catalina.core.StandardContextValve.invoke（StandardContextValve.java:191） at org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java:127） at org.apache.catalina.valves.ErrorReportValve.invoke（ ErrorReportValve.java:102） 在org.apache.catalina.core.StandardEngineValve.invoke（StandardEngineValve.java:109） 在org.apache.catalina.connector.CoyoteAdapter.service（CoyoteAdapter.java:298） 的組織。 apache.coyote.http11.Http11AprProcessor.process（Http11AprProcessor.java:861） at org.apa che.coyote.http11.Http11AprProtocol $ Http11ConnectionHandler.process（Http11AprProtocol.java:579） at org.apache.tomcat.util.net.AprEndpoint $ Worker.run（AprEndpoint.java:1584） at java.lang.Thread。運行（Thread.java:619）PrimeFaces錯誤StateHelper

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.

我使用primefaces 2.0.0 RC
是的，PrimeFaces論壇確認PrimeFaces 2.0需要JSF 2.0。此外，PrimeFaces 1.x不再受支持，因此如果您無法升級到JSF 2.0，則無法使用PrimeFaces。 – Sean 2011-01-20 19:03:51
