process failed when applying built model for test data

I was trying to build several types of classifiers, including SVM, Naive-Bayes, and Neural Network. The training processes for these models have been finished successfully. However, when I try to apply the built model for testing purposes, some of them are failed. In specific, the trained SVM model can be applied to the testing set as normal. However, the process gets failed when applying trained Naive Bayes model to the test data set. I launched the Rapidminer process as follows, which are the same for different models
java -Xmx30g -jar "C:\Program Files\Rapid-I\RapidMiner5\lib\rapidminer.jar"The error message was like
The model application workflow are the same for different models, except that we use different models. The workflow is here

the process you have posted is not complete, probably the max size of the post has been reached. However, the output says: As you can see, that happened in the Performance operator: So obviously your test data does not contain a label, but nevertheless you are trying to measure the performance. Since all your classifiers are supervised learners, the performance can only be measured by comparing the prediction and the original label. So you have either to make sure that your data contains a label, or you can't estimate the performance on the test set.

This gives me a bunch of warnings: And using the decision tree I get these errors: Can I somehow add the list of attributes generated from the training set to one of the test set tho avoid this problem.
My process file: I hope you can help me!
PS. I have deleted few tings from the process file in order to have less that 20.000 characters
This ensures that the attributes used to build the model from the training data are the same when the model is applied to test data.

I could also solve the problem by connecting the words of the testset to the operator, which preprocess the trainingset. My problem now is that I don't understand WHY I need to do that.
A classifier is in the end a mathematical function, containing of numbers and operators. After be trained, it doesn't need any attributes of the trainingset anymore, right? After training, the parameters, like C, are set, so it only needs to read the unknown X of the testset and compute the result, which is the label.
So why does it need the words of the testset?
Can someone may help me to understand that?
Does that help?

Marius
