The resolution to JBSEAM-1294 has brought out another NPE exception condition.
------------------------------------------------------------------------------

                 Key: JBSEAM-1551
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1551
             Project: JBoss Seam
          Issue Type: Bug
    Affects Versions: 1.3.0.ALPHA
            Reporter: Chris Rudd


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;
    }
