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

                 Key: SOLDER-309
                 URL: https://issues.jboss.org/browse/SOLDER-309
             Project: Solder
          Issue Type: Bug
          Components: Servlet
    Affects Versions: 3.1.0.CR1
            Reporter: Ove Ranheim
             Fix For: 3.1.0.Final


The ImplicitHttpServletObjectsProducer.getHttpServletResponse() produces a null instance when invoked from an @Observer.

{noformat}
public void observeHttpRequest(@Observes @Initialized HttpServletRequest request, HttpServletResponse response) {
    final String path = request.getServletPath();
    
    // Only manage contexts for authorized users 
    if (identity.isLoggedIn()) {

        // Redirect user to dashboard if landing page is request
        if ("/index".equals(path) || "/index.jsf".equals(path)) {
            log.infof("Authorized request to: %s. Will be redirected to home!", path);

            try {
                response.sendRedirect(request.getContextPath() + "/home");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
