    Getting "Stack must not be null" error when running a test

    Jeff Mutonho Newbie

      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 :
