NPE when using SeamTest (v2.0)

[igx89]

I have the following test class:

package com.fl.bpm_ui.scheduler;

import org.jboss.seam.core.Manager;
import org.jboss.seam.mock.SeamTest;
import org.junit.*;

public class InitialCallTest extends SeamTest
{
 @Test
 public void testNumberGuessWin() throws Exception
 {
 String id = new NonFacesRequest("/scheduler/usher.seam?flow=initialCall")
 {

 @Override
 protected void renderResponse() throws Exception {
 CallManager cm = (CallManager) getInstance(CallManager.class);
 assert Manager.instance().isLongRunningConversation();
 }

 }.run();
 }
}

And get the following error:

-------------------------------------------------------------------------------
Test set: com.fl.bpm_ui.scheduler.InitialCallTest

Running through the debugger, it seems the NPE is happening on the "FacesLifecycle.endRequest(externalContext);" line in the finally block in the run() method.

Any ideas how I can fix this?
