org.ajax4jsf.config.ParsingException: No filter mapping set for a filter

It goes something like this:

ERROR [[/WaSFP]] Exception starting filter richfaces
javax.servlet.ServletException: Error parse web application config

Caused by: org.ajax4jsf.config.ParsingException: No filter mapping set for a filter richfaces
        at org.ajax4jsf.config.WebXMLParser.init(WebXMLParser.java:131)
        at org.ajax4jsf.config.WebXMLParser.init(WebXMLParser.java:199)

It seemed strange, because I had defined a filter mapping and It worked for me before, so why not now? I had something like this in my web.xml:

    <!-- Richfaces configuration-->
    <context-param>
        <param-name>org.richfaces.SKIN</param-name>
        <param-value>blueSky</param-value>
    </context-param>
    <filter>
        <display-name>RichFaces Filter</display-name>
        <filter-name>richfaces</filter-name>
        <filter-class>org.ajax4jsf.Filter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>richfaces</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
    </filter-mapping>
    <servlet>
        <servlet-name>Faces Config</servlet-name> <!-- wrong, 'Faces Servlet' here-->
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Config</servlet-name>  <!-- wrong again, 'Faces Servlet' here-->
        <url-pattern>*.jsf</url-pattern>
    </servlet-mapping>
