Sorry, I missed what you were saying. I'm not actually trying to delete
Bean A though.
It's remaining, just the associated Bean B objects need to be removed.

Actually I am calling 'remove' only once for BeanA. The "cascade delete"
takes care of iteration. I had to set 'cascade delete' only on BeanB.
