No, the app is single thread, quite "clear", no experiments...
Here is the "self contained" variant of war (with no dependencies to
oour app server):

I guess to some library which the application is depend on (in
combination with Tomcat libraries ??), but I have no tools and
experiences to deterrmine it.

That's really showing that it's gone beyond the Tapestry code and back into
the Tomcat (catalina) code. Are you doing something tricky with threads,
like trying to do part of the render is a background thread?
You'll probably need to single-step down ingo the catalina code to see
what's exactly going on. Not enough information here to diagnose.

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.
