I tested various variable orderings with the standard example and didn't encounter any problems. Since I'm not able to reproduce the problem without additional input, I'm closing this thread. If the problem is repeatedly encountered, please submit a new bug report.

The passing of inteegers to the reader does not work as described in the user's manual.
Code example 30 (manual, page 33) is wrong.
The reader in version 4.0.x actually expects all variables to be provided as floats.
The correct example 30 is therefore as follows:
Int_t localDiscreteVar;
Float_t localFloatCopyOfDiscreteVar, localFloatingVar, locaSum, localVar3;
reader->AddVariable(...

The following two Reader functions are deprecated and do not work in versions 4.0 and higher. The input float or double vectors are simply ignored.
Double_t Reader::EvaluateMVA( const std::vector &, const TString& methodTag, Double_t aux);
Double_t Reader::EvaluateMVA( const std::vector&, const TString& methodTag, Double_t aux);
Please use another EvaluateMVA function...

The Reader does not check the type of variables that are passed to it via Reader::AddVariable.
This is unfortunate since the reader seems to expect float variables, even if in the training the variable was passed to the factory as an integer (This needs still to be verified).
The documentation in the user's guide is not very helpful here. Code example 23 (page 33) suggests that it is o.k...

I recently updated old code by expanding my ntuple and adding a few variables. I found that factory->AddVariable() does not work for the new variables unless they are added in the order they appear in the ntuple. Initially, I just added the new variables at the end of the section of code using factory->AddVariable(), but that did not work. When I inserted the calls in the same order as the...
