The error was caused by declaring the view handler to be FaceletViewHandler in the web.xml
rather than FaceletPortletViewHandler.

Subject: richfaces portlet

I am trying to get richfaces working with Jetspeed, jsf and facelets. I started by copying
an existing jsf/facelets sub-project and made the following changes. The web.xml was updated
as follows:
<!-- Plugging the "Blue Sky" skin into the project -->
  <context-param>
   <param-name>org.richfaces.SKIN</param-name>
   <param-value>blueSky</param-value>
  </context-param>

  <!-- Making the RichFaces skin spread to standard HTML controls -->
  <context-param>
    <param-name>org.richfaces.CONTROL_SKINNING</param-name>
    <param-value>enable</param-value>
  </context-param>

   <!-- This is optional parameters for a Richfaces facelets based application -->
   <context-param>
       <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>
       <param-value>com.sun.facelets.FaceletViewHandler</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>

The project's pom.xml includes the richfaces repositories:
<!-- add richfaces repositories -->
   <repository>
      <releases>
          <enabled>true</enabled>
      </releases>
      <snapshots>
          <enabled>true</enabled>
          <updatePolicy>always</updatePolicy>
      </snapshots>
      <id>snapshots.jboss.org</id>
      <name>Snapshot Jboss Repository for Maven</name>
      <url>http://snapshots.jboss.org/maven2/</url>
      <layout>default</layout>
   </repository>
   <repository>
      <releases>
          <enabled>true</enabled>
      </releases>
      <snapshots>
          <enabled>true</enabled>
          <updatePolicy>always</updatePolicy>
      </snapshots>
      <id>repository.jboss.com</id>
      <name>Jboss Repository for Maven</name>
      <url>http://repository.jboss.com/maven2/</url>
      <layout>default</layout>
    </repository>

I added the new richfaces portlet to default-page.psml:
<fragment id="dp-2229" type="portlet" name="TdiPortal-richfacesPortlets::MyRichfacesPortlet">
       <property name="column" value="0"></property>
       <property name="row" value="4"></property>
    </fragment>

Here is the new richfaces-portlet-view.xhtml.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:rich="http://richfaces.org/rich"
      xmlns:a4j="http://richfaces.org/a4j">
<f:view>
<body>
<ui:composition>

  <h2>JSF Application with RichFaces built by Maven</h2>

      <p>Here is an example of default inputNumberSlider:</p>

        <rich:inputNumberSlider value="50" />

        <p>Here is "minimalistic" input:</p>

        <rich:inputNumberSlider value="50" showInput="false"
            enableManualInput="false" showBoundaryValues="false"
            showToolTip="false" />

        <p>Another variation of input:</p>

        <rich:inputNumberSlider value="500" width="500" maxValue="1000"
            step="50" showToolTip="false" />

</ui:composition>

</body>
</f:view>
</html>

When the default page is opened, the following error occurs:
Caused by: java.lang.ClassCastException: org.apache.pluto.container.impl.RenderResponseImpl
cannot be cast to javax.servlet.ServletResponse
                at com.sun.facelets.FaceletViewHandler.createResponseWriter(FaceletViewHandler.java:370)
                at com.sun.facelets.FaceletViewHandler.renderView(FaceletViewHandler.java:571)
                at org.ajax4jsf.application.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:100)
                at org.ajax4jsf.application.AjaxViewHandler.renderView(AjaxViewHandler.java:176)
                at com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:110)
                at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:100)
                ... 89 more

I'm running:
Richfaces 3.3.2.SR1
Jetspeed 2.2.0
Tomcat 6.0.20
Facelets 1.1.14
JSF 1.2

My richfaces sub-project includes the class com.sun.facelets.FaceletPortletViewHandler.java.
Any ideas of what is causing the class cast exception?

Thanks!
Sandi
