[jboss-user] [JBoss Seam] - IllegalArgumentException: Stack must not be null

[laksu]

Hello,
I am trying to cook my first component test:

public class CategoryInteraction extends SeamTest  {
  | 
  | 	@Test
  | 	public void testMest() throws Exception {
  | 
  | 		new ComponentTest(){
  | 
  | 			@Override
  | 			protected void testComponents() throws Exception {
  | 				String result=(String)invokeMethod("#{categoryAction.nevv('E')}");
  | 				assert result.equals("categoryDefine");
  | 			}
  | 		}.run();
  | 	}
  | }
I get this weird stack trace:

I went to debug it to some level: It looks like Manager object is not initialized properly or something.

I am using Seam 2.0.1.CR1
