[jboss-user] [JBoss Seam] - Getting "Stack must not be null" error when running a test

[ejbengine]

The code for my test  is :

  | public class FindClaimTest extends SeamTest {
  | 
  | 	@Test
  | 	public void testFindUnregisteredClaims() throws Exception {
  | 		new ComponentTest() {
  | 			
  | 			protected void testComponents() throws Exception {
  | 				invokeMethod("#{registrationFinder.find}");
  | 			}
  | 			
  | 		}.run();
  | 	}
  | }


However, when this test runs , its failing with the message "javax.el.ELException: javax.ejb.EJBException: java.lang.IllegalArgumentException: Stack must not be null"


The full stacktrace is  shown below :
