I thought genericDao and categoryDao will be the same by the fact that
categoryDao is passing to GenericManagerImpl. If they are the same then I
can simply cast genericDao to CategoryDao and use its
getTopLevelCategories() method.

We can change genericDao to protected, but I don't see how it solves
your problem. This interface doesn't have the
"getTopLevelCategories()" method, so you'll still need to set your
categoryDao.
