Paul, 
   things are working again , thanks for your help. Where I was running into
trouble was that looking at the debugger, the field shows up as null up
until the point the field is accessed for the first time (at which point the
whole lookup of the injected field seems to occur). So, in the debugger the
field was showing as null, and then the page render was failing for other
reasons (e.g. for a while, incorrectly set up mocks, at other times, I was
missing the .tml in the right package), but it was harder to see as the
stacktrace only shows up in the rendered page (on which I was asserting). 
 
   The next thing I'm trying to work out is use  Testify for unit-like
testing. The idea was that I could possibly instantiate the page class
myself (e.g. w/o having to ask the tester to render the page), inject the
dependencies (using tester.injectInto(pageInstance) ) that are needed for a
particular method and then just invoke the method. I do see the
SimpleObjectsForComponentStore.put(..) being called in the set up phase
before the test case executes. However, using this approach, when I call
tester.injectInto(page) the SimpleObjectsForComponentStore.get(..) is never
called and as a result the test fails w/ a message that "No service
implement the interface...". Can this be made to work in some way using
Testify ?

Here's the test case: 

public class StupidPageTest extends AbstractZdTapTest {
   @ForComponents
   UserRepository userRepo;

   @Override
   protected void doSetUp() {
       userRepo = EasyMock.createNiceMock(UserRepository.class);
       System.out.println("The doSetUp() is called by TestNG");
   }

   @Test
   public void testElementIsOnPage()  throws Exception {       
       ZdUser testUser = new ZdUser(new EmailAddress("foo@bar.com"));
      
expect(userRepo.getUser(isA(EmailAddress.class))).andStubReturn(testUser);
       
       replay(userRepo);

       Document page = tester.renderPage("stupid");
       System.out.println("Page is : " + page.toString());
       Assert.assertTrue(page.toString().contains("I should be empty"));
   }

   @Test
   public void testStupidPageUnitTest()  throws Exception {       
       ZdUser testUser = new ZdUser(new EmailAddress("foo@bar.com"));
      
expect(userRepo.getUser(isA(EmailAddress.class))).andStubReturn(testUser);

       replay(userRepo);
       
       Stupid s = new Stupid();
       tester.injectInto(s);
       s.setupRender();       
   }
}
