> The the stock JSF converters require that he component parameter of getAsString not be null. The following is a code snipit from Param.getValueFromModel :
>    converter.getAsString( facesContext, facesContext.getViewRoot(), value );
> The code is using the view root as the component, which is null as ExceptionFilter.createFacesContext does not setup an initial UIViewRoot.
> I made the following change and it seems to have resolved the problem :
> ExceptionFilter.java
>   private MockFacesContext createFacesContext(HttpServletRequest request, HttpServletResponse response)
>     {
>        MockFacesContext ctx = new MockFacesContext( new MockExternalContext(getServletContext(), request, response), new MockApplication() );
>        ctx.setViewRoot( new UIViewRoot() );
>        
>        return ctx;
>     }
