Richfaces and Websphere Portal 6.1 Error

yashu.here Oct 7, 2010 12:46 PM

Hi,

I am trying use richfaces tree component in Websphere portal application which is running on WAS 7.0.0.9,

I could run the same JSF example on WAS 7.0.0.9 without any Errors, but when I add this into a portlet application I get following Error

Caused by: java.lang.NullPointerException

I replied to your post in the RichFaces forum, but i'll repeat it here. The problem is that the a4j ajax components are not wrapped by an instance of org.ajax4jsf.component.AjaxContainer or AjaxViewRoot, because you are using the IBM portlet bridge. If you use the JBoss Portlet Bridge instead then you can get around your problem.   Unfortunately I'm stuck with the IBM bridge at the moment, and I've got   the same problem. Wrapping the a4j:support component with an a4j:region   almost works, however, at least in my case, the whole page now refreshes onkeyup. I haven't yet figured out what to do about this problem.

Here's my jsp:
<%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@taglib prefix="rich" uri="http://richfaces.ajax4jsf.org/rich" %>
<%@taglib prefix="a4j" uri="https://ajax4jsf.dev.java.net/ajax" %>
<%@page language="java" contentType="text/html" pageEncoding="UTF-8" session="false"%>

<f:view>
<script src="#{facesContext.externalContext.requestContextPath}/faces/rfRes/org/ajax4jsf/framework.pack.js"
          type="text/javascript"></script>
<script src="#{facesContext.externalContext.requestContextPath}/faces/rfRes/org/richfaces/ui.pack.js"
          type="text/javascript"></script>
<link rel="stylesheet" type="text/css"
        href="#{facesContext.externalContext.requestContextPath}/faces/rfRes/org/richfaces/skin.xcss"/>
<h:form>
    <h:outputText value="Enter message: "/>
    <a4j:region>
      <h:inputText size="50" value="#{echo.text}">
        <a4j:support event="onkeyup" reRender="msg"/>
      </h:inputText>
    </a4j:region>
    <h:outputText id="msg" value="#{echo.text}"/>
</h:form>
</f:view>

faces-config and web.xml are attached. Let me know if you make any further progress.

I tried by adding all java scripts in portlet jsf page, but still ended in Error which says it is failing to find Richfaces variable.
It is related to java script, hence this is showing up as a java script pop-up.
Any help on this is greatly appreciated.
