Exception in Seam Resource is Swallowed and Redirection to debug.seam Does not Work
-----------------------------------------------------------------------------------

                 Key: JBSEAM-4435
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4435
             Project: Seam
          Issue Type: Bug
    Affects Versions: 2.2.0.GA
         Environment: Linux, JBoss 5.1.0.GA
            Reporter: Elmar Weber
            Priority: Minor


When a Seam managed resource produces an exception the exception is swallowed, i.e. it is not logged. Furthermore, maybe this is also the source of the problem, the failed request is not redirected to the correct debug.seam URL. 

Steps to reproduce on JBoss 5.1.0.GA with Seam 2.2.0.GA:

 1. create a Seam resource that produces an exception (code at the end)
 2. navigate to the Seam resource: /seam/resource/myresource

Now instead of redirecting to /debug.seam?cid=<CID> the browser redirects to /seam/resource/debug.xhtml?cid=<CID> which of course does not exist, thus resulting in a 403 HTTP error.
Furthermore the exception is not logged in the JBoss logs.
When you manually navigate to /debug.seam?cid=<CID> the full exception trace is shown (serves also as a workaround).

Example resource (requires existence of resource servlet in web.xml):

@Scope(ScopeType.APPLICATION)
@Name("myResource")
@BypassInterceptors
public class SimpleExceptionResource extends AbstractResource {

    @Override
    public String getResourcePath() {
        return "/myresource";
    }


    @Override
    public void getResource(final HttpServletRequest request,
            final HttpServletResponse response) throws ServletException,
            IOException {

        new ContextualHttpServletRequest(request) {
            @Override
            public void process() throws IOException {
                doWork(request, response);
            }
        }.run();
    }


    private void doWork(HttpServletRequest request, HttpServletResponse response)
            throws IOException {
        response.getOutputStream().print("" + 0 / 0);
    }
}
