I got IllegalArgumentException using SeamTest when @Begin method
My test code is below
public class MenuCtrlTest extends SeamTest {
@Test
public void testLevOne() throws Exception {
new ComponentTest() {
protected void testComponents() throws Exception {
assert (Integer)getValue("#{menuCtrl.getLevOneMenuItemList().size()}") == 0;
}
}.run();
}
}getLevOneMenuItemList() is annotated @Begin , when I run test ,it throws this exception:

net.coms.action.users.test.MenuCtrlTest.testLevOne(MenuCtrlTest.java:20) [testng] ... Removed 30 stack frames
then I remove @Begin of getLevOneMenuItemList() , test will be success.
My question is how to test, when it is a @Begin method?
