Test Set Problems in Knowledge Flow

I'm having problems with the test set component in Knowledge Flow. It
seems to work when the data is in the same order as that in the test
file, but not otherwise. There are no error messages when it doesn't work.
I saw that somebody asked a similar question before, but got no answer:-
"1) All classes are represented in the test-set AND
2) The classes are introduced in the test-set in exactly the same order as
they were in the training-set. "
Does anyone have an answer to this? What I really want to do is put a
new file with the outputs missing through the prediction appender, but
pretending it is a test set is the only way I've found of doing so. Is
there a better way? Having no output values seems to upset the test set
