java - JSF a4j + tomahawk + ​​myfaces 错误 : Resources framework is not initialised, 检查 web.xml 的过滤器配置

Question

我正在尝试使用 <a4j:commandLink>在我的 JSP 中，我收到以下我根本不理解的错误:

Exception while calling encodeBegin on component : { Component-Path :  [Class: org.ajax4jsf.framework.ajax.AjaxViewRoot,ViewId: /pages/clienteAM.jsp]  [Class: javax.faces.component.html.HtmlForm,Id: clientesForm]  [Class: javax.faces.component.html.HtmlDataTable,Id: cityList]  [Class: javax.faces.component.UIColumn,Id: j_id88]  [Class: javax.faces.component.html.HtmlDataTable,Id: telefonos]  [Class: javax.faces.component.UIColumn,Id: j_id89]  [Class: org.ajax4jsf.ajax.html.HtmlAjaxCommandLink,Id: j_id91]}Caused by: javax.faces.FacesException: Resources framework is not initialised, check web.xml for Filter configuration

My web.xml look like this:

取自 RichFaces documentation :

There are some problems with different filters defined in the web.xml file clashing. To avoid these problems, the RichFaces filter must be the first one among other filters in the web.xml configuration file.

尝试更改您的 web.xml 文件，以便您的 RichFaces 过滤器(又名 Ajax4Jsf)位于您的 extensionsFilter 之前。
