stateless (stateful='false') Form component throws Stale session

I'm a bit stuck implementing a login screen.  In particular, what
incantations are needed at logout to tell Tapestry to stop complaining about
no session being present at next login.  I've already specified
stateful="false" for the form:

	<form jwcid="@Form" listener="ognl:listeners.login" stateful="false"
delegate="ognl:beans.delegate">

But every time I logout I get the stale session error page.  I pretty much
copied what vlib does for logout.  But, unlike vlib, we return users
directly to the login screen.

	public void logoff(IRequestCycle cycle)
	{
		IMessageProperty home = (IMessageProperty) cycle.getPage("Home");
		home.setMessage("Logged Out");
		cycle.activate(home);

		Engine myEngine = (Engine) getPage().getEngine();
		myEngine.logout();
	}

In our engine:

	public void logout()
	{
		_killSession = true;
	}

	protected void cleanupAfterRequest(IRequestCycle cycle)
	{
		super.cleanupAfterRequest(cycle);

		if (_killSession)
		{
			try
			{
				HttpSession session = cycle.getRequestContext().getSession();

				if (session != null)
					session.invalidate();
			}
			catch (IllegalStateException ex)
			{
				// Ignore.
			}
		}
	}

Any pointers?

Thanks,
  == EE

If you search for "invalidate" in the list you'll find several postings
on this topic.  This one about engine.restart() was helpful to me:
