Hi
I have such problem: I have quite simple T5 application - (T5 +
hibernate), currently compiled under T 5.1.0.5. When I run it under
Jetty (ver. 8.0.0), it runs fine.
But when I try it to start under Tomcat, I get NullPointerException that
(probably) indicates the underline request is null.
I tested it under Tomcat 6.0.18, 6.0.20 and 6.0.26. Tomcats was "pure"
installations - with no aditional libraries.
It runs under Java 6.18 on Win7, the same problem in on Linux and Java 6.16.
I could post application's war somewhere, but it is quite big (cca 28M
including libraries), ant it requires our application server running
anywhere in LAN to run.
Here it the eception:

The code fragment cause it:
-------------------------------------------------------
@Inject
private RenderSupport rsup;
@Inject
private Request request;
@AfterRender
public void afterRender(MarkupWriter wr) {
boolean requireLogin =
request.getAttribute(Constants.REQUIRED_LOGIN_RQATR) != null; //
here the NPE is thrown, but the "request" is not null
if (requireLogin) {
rsup.addScript("$j(function() {");
rsup.addScript("$j(\"#loginFormDialog\").dialog(\"option\",
\"modal\", false);");
rsup.addScript("$j(\"#loginFormDialog\").dialog(\"open\");");
rsup.addScript("});");
}
}

Thanks for any ideas.
