Hi,

I have same problem. I don't like solution with HTTP redirect to page
that return 404 also. This solution is not fully logic from user
perspective. I would like to by able to show error404 without any redirect.

I have tried in onActivation method code:

response.sendError(404, null);

where:

  @Inject
  private org.apache.tapestry5.services.Response response;

It works in jetty, but didn't work in Tomcat ;-). I hope, that somebody
will help.

Regards

Jan
