Sr if this is the inappropriate place to post this kind of information.
As I tried to use KernelPCA with my classification problem, I could not apply trained model to test instances. The message "The example set contains attributes in different order than on creation time...." appeared although the attributes set are exactly the same.

I am not sure whether this is a bug or not.
Hope that help!

this is definitively a bug, since Strings are not the same even if they equal. I corrected this.
