Hi, I'm using JSF with Facelets and I'm trying to use standard error pages but they doesn't seem to work with facelets, only in normal JSP pages. Is this combination valid? if not, how facelets is supposed to handle error pages ?

Any idea is welcome.

Here is my web.xml:

Code:
   <error-page>
 	<exception-type>javax.faces.el.EvaluationException</exception-type>
 	<location>/AppError.jsp</location>
   </error-page>  


   <error-page>
 	<exception-type>java.lang.Exception</exception-type>
 	<location>/AppError.jsp</location>
   </error-page>  
   <error-page>
 	<exception-type>java.lang.Throwable</exception-type>


 	<location>/AppError.jsp</location>
   </error-page>
   <error-page>
     <error-code>500</error-code>
     <location>/AppError.jsp</location>
   </error-page>

And my facelet page:

Code:
 <!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:f="http://java.sun.com/jsf/core"

       xmlns:c="http://java.sun.com/jstl/core"

       xmlns:h="http://java.sun.com/jsf/html"
       xmlns:ui="http://java.sun.com/jsf/facelets">

 <head>

 	<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
 </head>
        
 <body>               
 	<h:form id="myForm" >
     <h:commandButton value="Cause a NullPointerException" actionListener="#{authorizationBean.doSomethingNull}"/> 


 	</h:form>
 </body>
 </html>

It calls a authorizationBean.doSomethingNull method that explicitly forces a NUllpointerException to be thrown.


AppError.jsp is a plain JSP page:

Code:
 <%@ page isErrorPage="true" %>
 <HTML>
 <HEAD>
 	<TITLE>Error Information</TITLE>
 </HEAD>
 
 <BODY>
 
 An error occurred during processing!<br><br>


 
 </BODY>
 </HTML>
And the exception displayed on the App Server console and not properly handled by the Error page is :

[1/19/09 15:26:26:681 CST] 00000028 jsf           E com.sun.faces.lifecycle.InvokeApplicationPhase execute /index.jspx @20,116 actionListener="#{authorizationBean.doSomethingNull}": java.lang.NullPointerException: Just a test...

We've done this kind of thing with no problems.  I recall there was a discussion, perhaps on the Sun JSF forums, concerning a bug with some combination of JSF implementation and application server where the exceptions were being wrapped in ServletExceptions (or something) and then not being interpreted properly by the container for the error page mechanism.
