------------------------------------

I would like to see this reopened.
As i wrote to the list, it does not work for me. I did integrate the use case example in my application, but when i hit the test pages submit button - the arithmetic exception is thrown - but a null pointer exception is thrown too, because my FacesContext dissapeared, i don't know why its gone - but its not there anymore after hitting the button to trigger the exception.

clay based exception trace snippet:

 java.lang.NullPointerException: context
        at javax.faces.component.UIComponentBase.getRenderer(UIComponentBase.java:738)
        at javax.faces.component.UIComponentBase.getRendersChildren(UIComponentBase.java:307)

        at javax.faces.webapp.FacesServlet.service(FacesServlet.java:138)
        ...

jsp based:

ERROR http-8080-Processor23 javax.faces.webapp.UIComponentTag - Faces context not found. getResponseWriter will fail. Check if the FacesServlet has been initialized at all in your web.xml.
ERROR http-8080-Processor23 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/myapp].[jsp] - Servlet.service() for servlet jsp threw exception
 java.lang.NullPointerException
        at javax.faces.webapp.UIComponentTag.setupResponseWriter(UIComponentTag.java:929)
        at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:310)
        at org.apache.myfaces.taglib.core.ViewTag.doStartTag(ViewTag.java:70)
        at org.apache.jsp.jsf.test_jsp._jspx_meth_f_view_0(test_jsp.java:100)
        ...

web.xml context param looks like this:

<context-param>
		<param-name>
			org.apache.shale.view.EXCEPTION_DISPATCH_PATH
		</param-name>
		<param-value>/jsf/error500.html</param-value>
</context-param>

The error page itself is displayed correct but empty if i call the page without an exception, so this should not be an issue.
Any help is welcome.

> When using shale-core for the s:token tag in my myfaces webapp, shale is eating 500 errors. That means if for example
> a Nullpointer Exception occurs, it doesn't let tomcat use the custom error page configured in the web.xml for 500 errors.
> If I remove shale-core from my webapp, everything works fine and the custom error-page is displayed.
