java.lang.IllegalArgumentException: can only set expectations on mock objects

This is a wierd error which really does not have a prescriptive solution. When it occured to me I just meddling with the Test Code adding the @After annotation along with a tearDown method which was not there earlier. Magically it worked. It now works even without a @After method.

My environment is a class that extends BaseManagerMockTestCase from Appfuse. Other threads that are out there do not give a complete solution either:
